really a nice gun, these are my thoughts on it.

stock is a dbl. rifle stock.

sights are a later addition, to my eye at least.

barrels are cut at one point, i would expect at least 28"

a 10 drams charge dont sound like a shotgun charge to me, i think it is a paradox rifle that has been toyed with, someone here should buy it so we can get some info about it.

best regards
