Yes, Mario, that is the Caywood bayonet. On caywoodguns site must look under "current flintlocks available" to find photo, and that is the 2nd fusil they show. Thanks for telling me about the de Witt Bailey book. My booklist said I had one, but searched all over until I found it stuck in with my Michigan gun stuff. Still looking for that bayonet in it, will look again. Suppose if I ever get the Caywood gun it will be a nice inauthentic .50 or .54 cal rifle w wood patchbox, hard on the purist's (I was once) digestion but I need a shootable rifle with a barrel of appropriate steel grade. Have a Pedersoli flint rifle, quenched & tempered steel, better than used in Trapdoor Springfields, but something squirrely about that barrel. Been shooting rifled muzzle loading guns off & on for over 50 years, couple originals, modern with maybe 4 different make barrels, never had one to string the shots up and down like this one. Or load like there is a tight spot in the barrel. Time is getting too short to mess around with guns that don't work. Rambling.
