D0n't see any indication of underbolting (no slots in barrel lugs); just the Kerstner top bolt. It looks like a Merkel 200e to me. I agree with Larry bumping his price a bit from 1500. I gave that for a very nice 12 ga with a lot of color on the frame, no cheekpiece. I would think a small gauge would do somewhat better in a market where the customary asking is around 2K for a 12.
