Thank you so much, Fernando, you're just great:
Yes, this is the one I was talking about!
And here is the original Österreichisches Kürassier-Tromblon M 1759
, the very model that the barrel was taken from.
Barrel length 65.6 cm, bore at muzzle 44 mm, at tang 26 mm.
I hope that Tobias Capwell has fun taking the measurements of the barrel of the Wallace 'wheellock blunderbuss' ...
Scanned from Peter Krenn, Die Handfeuerwaffen des österreichischen Soldaten
, Graz, 1985
I deaccessioned Baxter's Blunderbusses
a few years ago from my library just because there was not one single honest and
early piece in it.
