Crazy what you find for sale, look at this 20ga.

It’s a modified Trojan, forearm changed to a release vs. snap on, receiver reshaped, top rib modified…..quite the albatross.

That’s a wild ride and someone went to a lot of work for what reason? Be interesting to know the history behind that gun.

The seller says "It's a mistery". I've seen that rib somewhere, but don't know where. Eight thousand sales and doesn't own a bore micrometer. Just your average gun dealer.

5280 Armory is about three miles from my house. It's primarily a pistol-oriented gun shop and indoor shooting range along with specializing in black gun type rifles. What I'm surprised by is that they even have something like this modified Trojan in their shop, let alone have anybody that knows anything about vintage American SxS shotguns. As far as them having a bore mike, I doubt anyone there has ever heard of one, let alone would know how to use it.

This may have something to do with the lack of a bore micrometer Bill.

Looks like some amature was trying their hand at custom gun modifications.
And I'm sure it is a mystery to them...
