When it comes to insulators, you think you seen em all. I have never seen one like this. Obviously a tramp piece with no name, kinda reminds me of a christmas tree. Perfectly mint condition. This looks a lot like a U-206 but a little shorter with a flat dome. Apparently these are fairly common.

Ok, how about $5 + 5.50 shipping? Please see my other insulators. Almost all have been reduced to move so I can add new pieces!
