Nice cart, Thanks for the pix!

I'd love to see the shape of the barrel at the muzzle, is it round?
What Does the trigger flag do? I think I wrote that the sidelever I photographed had the set-trigger patent, and the lever, but no set-trigger.
I love that clam-shell engraving in front of the lever/guard!

Somewhere around here I have a package full of those "World's Largest Buttplate Screws". When you remove then you'll see what I mean.

Congrats and keep us posted!
