I think from sometime in the early to mid 1970's. I have a large pile of their ammo trays which I like very much. I haven't seen them in stores for a very long time. Seems like every time I've gone to a gun show I luck out and get another one or two. A couple of the ones I have have been in my possession since the early 1960s. Before that what trays I had were home made wooden ones. Still have those as well.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
