Looking for a barrel bushing for a FN 1910 (Browning) .380. This is the small knurled ring with the two small bayonet lugs that fit into the inside of the slide. I know this is a long shot, as neither Numrich or Popperts have any. I don't know the part # as the schematic at Numrich shows the 1922 model, and not the 1910 model. Any help appreciated. Doesn't have to be new, I need one for a machinist buddy to work with to make a custom spanner tool to facilitate the removal and installation of the bushing. If you have ever field stripped one you know what I mean wanting a special tool.
