I'm not sure if this is the correct place for this post...
On Sept. 20, 1970, a National Guard Armory in Newburyport, MA was broken into and robbed of "guns and ammunition." Some reports say that radios and explosives were also stolen; some reports state that all of the stolen items were recovered.
Question: what type of weapons (rifles, handguns, etc) would have been in that armory at that time?
