Some notes about the gun that are not evident due to the poor photo quality are:
There appear to be sulphur inlays in the patchbox and finial holes. The finish over them has darkened and crazed which makes it difficult to see in these pictures. The engraving on the patchbox on the end toward the buttplate is in the triangular shape of a viper's head. There are holes in the stock ahead of
the trigger guard where an inlay had been just like the one next to the ramrod inlet pipe. Dr. Whisker advised that the lock is a commercial Bedford lock.
The remnants of a signature are on the barrel. The name starts with a capital script D with a loop on the top of it. The loop has a dot punched in it. Also
evidence of two other loops in the signature with dots punched in them.
