I have 2 older JLD built rifles with German trunions , but it's very possible that yours may have a German one. They eventually started using U.S. parts ; especially now more than back in Conn. The good news is, that as long g as your flutes are properly cut and it shoots reliably; you have a very accurate 16" match barrel that will hold much tighter groups then the thinner profiled barrels. I have 2 JLD 16" K,s ,1 with a Wilson match and 1 with a Thompson center match, both are extremely accurate. Enjoy, I'm sure your fine. Wide forearm and A3 stock is of more value and collectable.
