I just recently acquired a nice No5 Mk1 Jungle Carbine dated 8/47. I originally was thinking the No5 bayonet would be correct for it then noticed that the No7 seemed to have been designed to fit it as well. I quickly noticed too that the No5 bayonets are not particularly plentiful and at least one I looked at was priced close to what I paid for the rifle. There seem to be more of the No7 bayonets around and the price is somewhat lower. I would like what I buy to be correct for the 8/47 manufacture date. Any help, comments/suggestions are greatly appreciated. I have seen several vendors advertise a reproduction No5 bayonet. It seems to be the same exact item offered by all of them ranging from $60 to just over a $100. In the adverts they toss around "Ishapore" I'm skeptical and would probably pass on the repro.
