Since I found this insulator some have expressed interest in it. So I am bringing it to Springfield to sell. I have heard various ranges of worth so I'm taking offers. Here's the specs. The pin is inert it will not come out. It has a small bite out as seen in picture. And some small dents in metal cap. You can examine it in person. I will be at show SAT. 9 am to 1 pm. Thanks!
