Hey Jack,
Interesting. Just going from memory, the 16 I saw seemed
newer than the GB Superfixe. The 16 had Charlin only stamped
in the middle of the top lever. No model name was on the top lever.
Also condition of the metal seemed much better--wasn't
frosted like the GB gun. Wood on the 16 had the same lovely red hue as the GB
gun--very pretty. The guy selling it mentioned that the gun was part of an estate
collection that was mostly rifles.
I don't own a sliding breech gun, in fact know very little about them.
I do have a fascination with the mechanics of the action (as well as the MF Ideal action) though.
A guy never knows what will be around the next corner at a gun
show. Guess that's why I go.
