Thank you Everyone! That explains everything quite well! I really appreciate the responses.

I've been Lurking around here for sometime and faced a question on which I could use some guidance. I opened my box of powder funnels to pull out an "E" funnel to load 45 colt. The funnels are mostly used ones I've come across with an occasional decent price on ebay. I have 4 of these but in 3 different lengths and styles. are 2 of these knock-offs? or old styles? Any thoughts and info is greatly appreciated.
