Great thread and beautiful club butt.
I've been looking to acquire one of Day's guns for a couple years now and have yet to find one. As someone new to collecting and shooting flintlocks, I'm sorry I missed my window with him-by all accounts a good guy and good guns.
And his departure left collectors looking for quality early colonial guns (matchlocks, wheellocks, English locks, doglocks) with one fewer semi- custom / custom option in a collecting niche that was already fairly choice constrained and seems to be getting smaller by the day!
(I wish his sons well, but am told their waiting list is long and their projected start date has repeatedly slipped. Fingers crossed...)
