So I'm stumped on this one. The outside rim is duller than an INC red button, and so I am 99% sure it's an early Folmer with long knurling because of the shape and because this knurling pattern is only seen on a short knurled early Folmer, but I've never seen an early Folmer with long knurling before and I also have never seen this type of assembly on the rear before. Does anyone know what this is? Have you ever seen one like it before? Thanks!
As of now, I'm calling it an early Folmer red button with long knurling which I've never seen before
