I need to fasten the two halves of this vintage 1930s/1940s Detroit Products #123 signal arm together. They came to me separated, w/o the original fasteners, in a rusty condition. From an original photo, it appears that the fasteners used were a smooth, round head rivet on both sides (“double-cap” rivet)? The hole diameter is 3/16”. The thickness of the two halves together is approximately 3/16”.
In addition, the name badge appears to have been fastened with the same type of smooth, round head rivet. The hole diameter is also 3/16”. The thickness of those two halves together is approximately ½”.
Can someone help me identify what was used originally in this particular application, as well as source the replacement fasteners and the setting tools required?
