Thank you all very much for your comments.

And I agree, it is too far gone to even try to make it look respectable again.

The bores looked very dirty but did not see any serious pits. But dirty enough that pits could well be present. The outside of the barrels do have some serious pitting however.

I will let the owner know what he has: a pathetic example of what used to be a very fine shotgun and its value is near zero (0).

And thanks again for your comments.

Jolly
