Here's a neat 1866 trapdoor that just happened to arrive on the same day my 1868 did! That was pretty nice.
The stock appears to have never been cleaned, sanded, worn or damaged. The face of the breechblock looks clean and I cannot see any indication that the rifle has been fired. Somebody. Smarter than me could tell you for sure!
The bore is absolutely Mint.
the front sight, tho unworn, is not as narrow at the top of the blade as is the front sight on my 1868 No. 6 rifle.
