Faked up guns are not news. Legit part for them is a little weird.

I was looking at a high grade, small bore, that is missing the fore end. I happen to have one and considered buying the gun and fitting it to the gun. I did not think that there was a need to send it out for engraving of the proper serial numbers, which seems to have been left of by the maker. But I can understand the temptation to do it because the sale price as is is about half the restored price.
