A Styrian wallgun with snap tinder lock, ca. 1525
The barrel struck with the maker's mark of Peter Hofkircher, Styria.
The lock with part plate of brass, only for the serpentine cock. The blackened full stock of limewood, with the muzzle section of the barrel left unstocked. The ramrod channel drilled a bit out of the middle to avoid contact with the recoil hook. The whole piece photograped standing upright against a row of matchlock wall pieces of mid 16th to early 16t centruy dates. Michael |

Good morning Michael.
Your excavated lock looks wonderful now. the 'before' pic. looks like it was about ready for the junk pile! Brilliant job in saving the 'life' of such an early and rare lock! The wall gun by Peter Hofkircher has some very interesting details. Can you tell me why the short lock-plate, with spring nailed to the stock,...when locks were being made with all parts mounted on the plate before this date? Economy measure? What calibre would such a wall-gun be? The off-set ramrod hole makes sense, but is it not rare for a wall-gun to be fitted with a ramrod? I thought I knew a little bit about matchlocks, but the more I learn, the less I know! I also note the use of limewood, It appears to have been rather common for stocks at this time. What characteristics does limewood posess, to make it desirable for gunstocks? Is it very resistant to splitting like beech, or some other property? I find it fascinating that limewood will still give off its aroma after 450 years! looking at the row of wall-guns, the butt-stocks look as varied as can be! it would appear that the artist was coming out in the men who did the stocking. Those with a very narrow butt-stock would be I think, rather painful to fire,...except for the wall hook. You do give me much to ponder!... R. |

Hi Richard,
I am afraid there is no certain reason for employing so-called part lock mechanisms at a time period when complete lock mechanisms were known long since. It may have been a regional thing, like an old arsenal armorer who may have preferred to cling to a form that he had become familiar with. Generally, during the first half of the 16th century, both 'obsolete' and 'modern' forms are found side by side. The overall length of the Hofkircher wall gun is 179 cm, the relatively small bore is 15,7 mm, the weight 6,7 kg, so there is really no need for a hook and the piece is quite light for a wall gun. It is very unsual for an early 16th century wall gun to be fiited with an ramrod, indeed, while there are many heavy pieces known from the mid-17th century to have their ramrods mounted to the left side of the stock, held by small iron pipes. As to the use of limewood, it is said to be easy to work on and quite tough at the same time. And - exactly, it does retain its beautiful aroma! A great variety of butt-stocks is found at the mid 16th century. Michael |

See what that sleeping Landsknecht guy has rested on his knees!
A 1530's matchlock harquebus with blued iron parts, brass tunnel back sight and heavily swamped muzzle section, the stock left 'in the white'!!!!

I have been meaning to focus on these wonderful threads by Michael one at a time and try to learn more on these medieval firearms, and today was one of those opportunities. I am such a neanderthal when it comes to the dynamics and complexities of firearms, that much of it is difficult for me to connect...however in reading the brilliant discourse between Michael and Richard it seems remarkably understandable.
Its like textbook medieval firearms with two brilliant professors presenting a completely captivating course, and with Michael's amazing photos, its as if I am looking upon and handling the actual weapons. In reading this, my only observations and questions are admittedly elementary, but I will state anyway. It does seem like the Thirty Years war did bring many innovations and changes in weapons production, along with obviously profound other effects and influences in many perspectives. I had never thought of exactly how long an element so simple as a buttplate had been around, and now I can better realize its purposes as well. I have always had an addiction to discovering such details and minutiae (thank you Michael for the note on that word ! and it seems that often such seemingly irrelevant things can offer important clues in investigating weapons and thier developmental forms. Excellent observations ,Richard on the screws, as noted by Michael (I think we should have a thread, no pun intended on screws as used in early weapons). I think we have discussed this briefly on screws used on sword hilts, but need to look more into the topic. I cannot help but wonder on these larger wall gun versions, if there was any problem with recoil. Would these have been like cannon used in naval situations, using lower charges due to closer quarters as the targets were so close? I am under the impression that firing these early firearms that the detonation on relatively uncompressed powder would not have produced very much recoil...would that be somewhat correct? Thank you so much guys for continually developing this fascinating field of study here!!! All very best regards, Jim |

Hi Jim,
I cannot but thank you very very much for your kind lines. Actually my passion feeds on such a brilliant counter part like Richard, whose demanding thoughts and questions really get me going. I have been thinking abouth a thread on the 500 years in the development of screws in European fine mechanics and posted a few pictures some months ago. I need to take more and better pictures but it is not forgotten. In discussing the bad recoil of wall guns one should bear in mind that the heavy weight of these pieces and the recoil hooks both acted as absorbers. On the other hand I can testify from my own experience that matchlock muskets kick quite hard too. I would compare their kick back to a 12 or 10 gauge shot gun. With all my very best wishes, Michael |

Hi Michael,
I look forward to examining the detail on variations of screws used by armourers in those times. Its funny, it reminds me a lot of Sherlock Holmes describing his treatise on burned tobacco, which he seemed almost obsessed with. Watson then made his comment on minutiae!! which has been with me ever since Good information on the recoil on these as well. I have not handled many firearms, so it is good to know that there was indeed recoil...ouch! Thanks very much Michael. All the best, Jim |

Jim, I'm not trying to pose as an expert in any sense, but looking at your question regarding recoil, I'd say the relative compaction of the powder isn't a major parameter in the recoil calculation, but certainly contributes to it in the form of whatever muzzle velocity the projectile obtains. If we are to believe the tests which have been done in recent years by very knowlegeable museum staff and others, there wasn't much difference in the muzzle velocities achieved by 16th. C. handgonnes and say smoothbore muskets of the 18th C., something like 450-550 m/s if memory serves.
Recoil is the result of the mass of the projectile and the velocity it obtains in the gun (m x v = momentum,) and is equal to the momentum of the projectile because that action has an equal and opposite reaction. The gonne is propelled rearward initially by the same momentum as the moving projectile has at the muzzle, but reduced by the mass of the whole gonne, which in those days was considerable (many were easily 50 pounds.) This resulted, I'm guessing, in a modest recoil since the relatively very heavy gonne starts rearward at a very low velocity compared to that of the projectile. The common belief is that the hook on the front of an arquebus or hackbut is necessary to convey the severe recoil to a solid wall or tripod, but I've always wondered about that. Perhaps if a gonner had to shoot the piece all day long in a siege situation, even a modest recoil would beat him up too much, thus the hook requirement. Some of the early hand-cannons that had relatively large bores, and short, light barrels, with only an iron tiller to hold it may have been very hard on the shooter. If we assume that muzzle velocity didn't vary too greatly, then the ratio of projectile weight to total gonne weight would give a good indication of relative recoil. |
