If the second set of barrels is numbered to the gun they could very well be factory. I've seen more than one Smith and Parker that had a damascus set and a fluid set. Guys had a gun with damascus barrels then when fluid came out, and was considered better, they sent their gun back to the company and had a fluid set fitted.

A friend has a D grade Parker hammer gun that has the same set-up and letters that way. Now that's quite a shotgun!
