Thanks for the compliment, Brokenpole. While I don't know how many experts there are on this forum, I am certain of one thing, and that is that I'm not one of them, because like you I learn new things all the time here. I like the word enthusiast, and if you don't mind, that's how I'll refer to both you and myself. Enthusiast: n. 1. One who is filled with enthusiasm; one who is ardently absorbed in an interest or pursuit. I think I can get away with stealing part of a hardware store chain's slogan, after all, they stole it; so "This Is The Place!" Here we can get it all, from the history of black powder ordnance, to the details of manufacturing contemparary reproductions in both miniature and full scale, and so many other aspects of this topic that fall in between.
