I here attach pictures of two early pieces; one a 'cão' (dog) from the end 14th beg.-15th century, in exhibition in the Portuguese Navy Museum and the other, his successor, a 'berço Manuelino' (so called cradle of King Dom Manuel) circa 1500, from the collection of Riner Daehnhardt.
Although they have not measurements notes, one can see that proportionaly their chambers are not that narrow nor that long.
I am not sure that the second chamber belongs in the berço but, if not, the period will be the same.

Thank for fernando! If these are 15th cCE or earlier, then that is a pretty firm 'no' to the question of whether a typological date is possible. The more I (and others) have searched, the more evidence has come up for this conclusion.

It is not what I had hoped, but I think I will have to settle for a broader 15th-late 17th century sort of time frame. I have learned more than if I had not asked though, so I will count things as a win regardless.

Rather complex subject indeed, taking into account a vast range of considerations like time line between different nations being distinct, with some adopting certain types and others not, and each one in its own period. The universe of typologies is huge and so are the locking systems, handles and all that.
See how slim is a "Esmerilhão" of the beg. 167h century, exhibited in the armoury of the Ducal Palace of Vila Viçosa, with a 3 cms. caliber, total length 186 cms. with a breech of 44 cms.
Then we have two of the seven bombard chambers used in the siege of Baza by the Spanish Catholic Kings in 1489. These have a caliber of 20,5 cms and a length of 142 cms.
An at last we have a chamber from the end 14th - beg. 15th century, in exhibition in the Portuguese Navy Museum. With a weight of 1450 Kilos, a length of 1,5 mts. and an exterior diameter of 42 cms. (38 cms. at the muzzle), it would have served a gross bombard or "Trom" of some 4 to 5 mts. length and a muzzle diameter of circa 1,5 mts.

Hi, Fernando
Thanks for posting these pics. The swivel rampart gun is most interesting, when I saw the image, something told me "I may have seen that before" and lo, there is a photo of its Far Eastern equivalent in a reference book on Chinese arms. A rather fuzzy black-and-white image, not worth reproducing here, but it shows something very similar to the Vila Viçosa example except for the length (2.2 m) and caliber (2.6 cm). The substantial points of difference on the Chinese gun are the fact that it is mounted on a wheeled 4-footed support, and that it is equipped with an actual matchlock mechanism with a trigger. It is dated 1727, making it about a century younger than the Portuguese counterpart in your photo.

In a prior post you use the term berço (cradle) to describe the breechloaders under discussion. The Chinese name for this type of gun is "zimujiang" or child-and-mother gun, the chamber piece corresponding to the baby in a cradle.

Lastly, the "scroll" shape at the end of the buttstock is almost identical to that seen on a type of Japanese matchlock "horse pistol" called a bajou-zutsu.

Yes Philip, a peculiar buttstock indeed.
I would not reject the possibility of this esmerilhão having a different origin, as so often museum personal fails, if it weren't for the fact that the legend states that, there is an identical example in the palace armoury and another one in the Lisbon Military Museum. It does not mention that identical also comprehends the sock shape but, let us believe so.
Curious analogy of the Berço with the Chinese "zimujiang" I was already aware that such connotation is not (only) of Portuguese inspiration. Also the Castillians call it 'verso', but i think i heard the attribution is French. But no doubt the term increased its popularity with King Dom Manuel personal development of this typology by having them forged in one only piece and prepaired for severe endurance; thus the name Berço Manuelino.

Fernando,
The similarity between the Portuguese and the Chinese examples of the breechloading guns can be explained by the fact that this type of gun with a chamber-piece retained by a "cradle" integral with the barrel is an introduction to the Far East by Europeans. Of course, the Portuguese were there first (although we must admit that the Dutch brought the same technology with them, later). Another name that the Chinese applied to the cradle breechloader was "folangji" or Frankish device. The Portuguese were the first Europeans to reach China in any numbers, and initially they were called Franks, after the Indian and Near Eastern habit of referring to Europeans as "firangi".

Portuguese breechloading cannon of the 16th cent. have a remarkable stylistic similarity to their Chinese and Korean counterparts of that period and later. The swiveling "lantaka" cannons of the Malay Archipelago no doubt have a similar origin, also noting that a few rare examples of those are breechloaders as well. You may have seen a few of those in private collections in Portugal as well.
