Correct Robert (CNKILLERCLOWN) not only did some extremely sloppy work, he actually damaged good parts. I remember one of his last works of art, he took a grinding wheel to a helpless 1928 Colt to smooth down a rivet. By the time he was done you couldn't use those parts on a dummy gun. Robert the clown killed that gun and messed up his business partner who owned the shop. I think the gun's owner eventually sent the completed gun to John McGuire who did an outstanding job of rebuilding and refinishing it. Robert would ask the experts on the forum about technical information, and then would post information on the forum like he was an expert. If you search the forum, you can read some of his reviews, here is one: CNKILLERCLOWN infoIf by railroad guy you mean Robert, well he disappointed a lot of people here and disappeared.
My ORF, and others, weren’t well prepared. They leak rust from the trunnion/plate interface and no amount of oil, short of submersion, has stopped it. It’s cosmetic
AFAIK Recon does not make those they sell.
Many years ago John McGuire built my 1st M1919A4.I think you mean John McGuire - another good builder.
