Well, I for one am jealous of your nice find. You don't list the barrel length, but there is no reason that it couldn't have been in some chunk shoots: people used to bring what they had.
Unusual that it doesn't have double set triggers, I take it that the single trigger that we see is a simple trigger.
The stock seems to end about 4 inches back from the muzzle. Does this look original, or was it modified at some point?
Anyway, lots to like about your "new" rifle.
