Ottoman bulbous barel wall musket

[eftihis]

Thanks for all the comments,well noted! It seems that this type of stock was a widespread stock in some point in Ottoman history arround 17th century. I dont know why, and I would like to ask Oliver if he can show any example of the Catalan guns this style is derived from.
We can see 3 muskets with similar stocks in H. Ricketts and P. Missilier, "Splendeur des Armes Orientales", Paris, 1988, pp.31-2. I believe this is the type of stock that dzefeder derives from.
Finally I attach a photo from a museum where among the shishane type of muskets there is one of this form.
