Austen SMG Barrel Collar w./Sling Swivel

...Oi,Oi,Oi.... Australian Austen SMG & Sten Mk2/MK5 SMG barrel collars are original and almost completely gone from the market.  We have just over a dozen remaining and then they are gone for good.  WW2 issue, these original parts are GI and unissued , still in cosmolline. Unlike the British Sten Gun, the Australians had modified the barrel collar to have a sling swivel attached which is ideal.
