I think I said "crude looking." Other than that, i don't know anything about them.
Looks pretty sweet to me, I’ll take 4 please.
The CIA and US Army Special Forces MACV-SOG operating clandestinely in Cambodia during the Vietnam conflict took a great liking to the Swedish K and Egyptian licensed clone 'Port Said' submachineguns as you pictured earlier. These weapons were 'sterile' and any capture of them by the North Vietnamese Army lent plausible deniability to their origin.
There once was an FR poster here named 'sneakypete' who had in his FR profile a scanned photograph of himself at a US Army Special Forces hilltop firebase in Cambodia in 1970 wearing a uniform with no identity tags carrying a Swedish K SMG like you posted. Maybe he'll pipe in and say something. :)
I would agree, those types of weapons seem conducive to long term storage if prepared properly...
When they mentioned “tire” in the article, it probably meant a “tube” that was sealed at both ends to reduce water or other corrosive seepage that would be a problem...
Why they put it by a “road side” is beyond me...
Probably thousands of little cashes like this all over the place over there...
