The S-2/3 section in my battalion in Vietnam had a small collection of obsolete types. One such was an M3 grease gun. M88 tracked recovery vehicles had a rack inside the hull for one of these, I think M48 crews had them. But otherwise, they weren't in use that I saw. I fired the one we had; they have a slow cyclic rate, like 450 rounds per minute, vice 800 +/- for a Thompson, M2 Carbine 750 +/-, and M16 which I think is also around 750-775, +/-.
I'm wondering how many of these might be in the legal population of papered automatic weapons in civilian hands. Surely none were released as surplus; maybe some PD's got some that later were re-sold into civilian hands.
I used to see Ljungman rifles for sale in the late 1960's in the larger shops that carried surplus arms. But they were all 8mm versions made for the Egyptians. I never owned nor fired one. I was more drawn to the German rifles. But I had a couple of the FN49's made for Egypt in 8mm, those were good rifles but heavy. Heavy used to never bother me, being as how I was used to K98 rifles. Everything was heavy back in those times.
