Old single shotgun, what is it?

[SKScanuck]

This belongs to a friend of mine. He brought it over for me to figure out what it is, other than in bad shape.....no markings except for what appears to be J.L. Fairara on the underside of barrel.

Any ideas?

looks like a Rook rifle that has been bored to 410 shot ga.

Have you disassembled it to see if there are any markings other then on the outside ?

Belgian rook rifle I have one in .320. Is it rim or Center Fire? I have one very similar, missing the butt
I'd be interested in buying it if it's not too pricy.
