A few of us are trying to find the parts to finnish this build. Small parts are welcome but the main parts are a bottom plate (original or repo), rear sight base and the ever elusive trunnion w/cover detent.
edit:A complete rear half of an original M37 was purchased from DLO (Doug).The trunnion has been found with a big thank you to the board. The last two parts are the Breech lock extractor cam and Right Belt holding pawl bracket. I had bought each of these as repo but they were manufactured incorrectly. Unfortunately, both are out of business.
Thanks
John
