Keeping on the cannon path

[celtan]

Thank you, Bluelake. Probably the quality and purity of the ingredientss (sources) in the 16th C would not have been the highest. So, we are left with BP that was effectively less powerful than what was available in the 18th C.

I've made bp and tested it alongside modern commercial types, using a standard ratio mix (75:15:10), along with some other ratios. I also used a binder (rice rinse water), which kept things from separating. However, instead of corning, I did a fine grind, which would have been similar to bp here in Korea back in the 14th C. I used a flintlock eprouvette and compared my powder to commercial powders (FFG-FFFFG) and the results were quite lopsided; my powder would register 1~2 on the scale, while the commercial was 3~5. I think that not only was separation a big problem, but also the ratio of niter/charcoal/sulfur. Still, I wouldn't want to be on the receiving end of either type

Hi Nando,

Are there any areas on the barrel that can point towards a later alteration like an iron fixing band (leaving a lighter surface area?)
It is interesting to think about how and where that tiller broke off/was sawn off. And what would have happened next.

Beautyfull example of an early hand cannon.

Hi Marcus,
This pattern is consistent with another one sold in some auction a few years ago. Only the length in such one is shorter.
The text in the offer mentioned a 'quadrangular cascabel' and not a 'cut off tiller'.
So at facing both examples, we don't have as a fact that, this is short tiller was meant to be like that from the beginning.
... or was there a generalized habit to cut them off for some modified purpose .
