I had a sigelei 13A a while back but ended up selling it. Well I got another one today and the bottom post and firing mechanism are completely different making me wonder if it is a B. The store I got it from swears it is a 13A. The original design, just like the # 8 was great. chrome over brass post with internal spring coming out from the top and the end of the button being metal. This is a copper spring wrapped around black what I hope would be delrin, and a plastic cap on this inside of the button. What?? Anyway, here it is. Can someone please clarify for me? Thanks so so much!
