It would be nice to see one of those Crandall 3" Tobins, to see if he altered the frame at all, or just added 3" chambers and called it good. I've seen plenty of lever way left Tobins, and have seen more than one with a bent frame.

I owned a 40 grade, 12 gauge, serial number 700, that a friend suggested I bore the tubes out to 10 gauge, and rifle one of them to open the choke. It weighed about 9 pounds.
I never got the gun shooting, I was still replacing parts and wood on it when someone asked to buy it for the barrels.

I have a hunting partner that still owns the black finish Tobin 12 I sold him, that I got from John Mann, and he uses it to great effect with 2 1/2 Vintagers, on pheasants. It required a shim on the hook, done by Mike Orlen, and I know for fact it is his favorite double.
Sometimes an old gun speaks to you. I have a Nitro 16 that gives me a good chuckle when everything goes right and we, the dog and I, get a bird with it.


Best,
Ted
