Added - 50 with long tab receiver cover latch - #5
I have been interested in the way the 50s changed. Thanks to info from various experts, I have tried to follow this change.
1. 50 with all 49 features including spike bayonet. This was in question until documentation was presented and another 50 with spike was found.
