Balkan gun with early turkish barell

[eftihis]

Thank you all for your comments! For me the most possible scenario is that this musket was built in a Venetian controlled area, using a captured ottoman barell and a lock from Venetian arsenal. However, the problem is i cannot trace this form of barell in manuscripts and icnography of the period (16th-17th c). Also althought this tye of barell is for sure early turkish. i cannot find it in Askeri museum objects. Also Turkish collectors whom i talked with, they dont know this design! Is it possible taht is a desigm manufactured somewhere in teh Balkans after the ottoman conquest? Here is another musket that uses this type of tylip barell (i thinh in a second use). It belonged to a Cretan revolutionary and is held in the historic-ethnological museum of Athens.
