It is a skeet gun and I can't even estimate how many zillion shells have gone thru it. I own a Krieghoff K32 (no.1761) that I bought it in 1962 as I remember. What gunsmith do you use, Pylinski, the guy in Jersey or Allem ? But that isn't the case with this new to me gun ! Well I think one K-80 unsingle trap barrel needed to be fit to my old reciever, but I don't know how many other K-80 and K-32 barrels and stocks slipped right on that old gun. All the K-80 and K-32 stuff I had tried to use on the K-32 I used to have slipped right on. But after we removed my stock we found that none of his later K-32 or K-80 stocks would fit my reciever without some slight inletting. I was at Danny Pattons shop yesterday as I planned to swap out the stock and forened for a set he had.
I have shot K32's for 40 years and have never shot anything I liked any better. They are difficult to work on since all the parts have to fitted depending on which parts are used and where.
The Krieghoff gunsmith I use told me that any K32 with a serial number below about 2400 could have from very few to almost all remington parts and the rest Krieghoff parts.
