Interesting. Unfortunately I no longer have them nor a M2 I had either. All my paper route money for years went to buy them. Back then you could buy them for $75-125. As I got older and started driving my interests turned to chasing skirts,so one by one the unused guns were sold off to fund used muscle cars (they were cheap too in the 70s) All in all I'd sooner have the guns than the cars today.
