OK, here goes "Nice picture!"

Mike

p.s. do you have a gun it fits?

It fits and I have shot them. They look like M21 barrels.

Good to hear they fit! Chambered for what? Any markings on the barrel?

Pretty sure it’s a rifled slug 12 ga., Hal.

What’s the length of the barrels, William? Are they a lot thicker and heavier than the shot barrels?
JR

26" 12 ga normal thickness standard markings

choke markings?

and Serial number on the barrel block?

I was hoping the the Archive records might have
a special entry for this barrel, SWEET!!

The elephant in the room others have had the courtesy to not mention is that without some sort of documentation John Oiln didn't have anything to do with it.

It's quite possible he did have this made for a friend as your word of mouth provenance states, but the onus of proof is on you.

We would all like to see it. Most of us would like to shoot it.

Other than that, what 'comments' can we give you?

Rt Imp-cyl; left Mod; serial 3797

Doesn't really add up Mr. A.

Had this been done as a bore rifle from the factory it would likely have started as standard tubes first, rifled, then profiled. It would have been struck so as to have thicker muzzles than a bird barrel.

It would then have been regulated with whatever the customer wanted as a slug load.

Any number of competent gunsmiths then as now can cut rifle a bird barrel. The wisdom of that is debatable. Winchester would certainly do that on the orders of the head honcho, the question is 'did they?'.

The serial number is 'possibly' correct for the 1930's, but as we know nothing is always with M21's.

It's an outside possibility that what you've been told is true, but it's a longshot in my humble opinion.
