This small victor is embosseed with a sand blasted R=∞ symbol, in a little multipart of course, with some numbers and patent (i think...) information under it. I'll post a closeup of the embossing after this. The insulator is pretty small for a multipart, not sure if that can be seen in the pcture but it's a little one. If it helps, that's a little bit of an M-2210 to the left
