There were three Jungle carbines produced:\
No 5 - Made by the British on a No. 4 Mk 1 - This was the one with the wandering zero problem. It was never corrected and before too much development went into it the SLR was issued and bye bye No. 5 - Easily identifiable by the peep sights.
No. 6 - Made by Australia on a No. 1 Mk. III action (SMLE). - Did not have a wandering zero problem. Was not produced in mass numbers, and as a result is about as rare as hen's teeth. - Easily identified by the ramp sights and lithgow manufacturing stamps (if it didnt have Lithgow on it, then its not a No. 6)
No. 7 - Cant remember who made it. It was a No. 4 Mk 1 in 7.62 NATO. No wandering zero on this one either. - Ishapore is probably the origin on this one. The previous poster had it 100% right on the Indian LE's, they were made a lot stronger to handle the 7.62 round. You can rebarrel an LE to 7.62 but you have to be extremely careful on what ammo you feed it. If you accidentally toss a .303 round intended for a vicars machine gun in there (identifiable by headstamp only) then you will almost certainly have a catastrophe on your hands (or your survivor's hands).
They all had cone shaped flash hiders though, so yours might be a fake...or it could have just been replaced with something else.
As everyone else has stated though, there are a lot of imitations out there so beware of buying one. I would highly recomend getting a few good books on LE identification and thoroughly check out the rifle you are looking at before putting money into someone's hand on it. LE's are fun to collect, shoot and will provide you with many hours of amusement just tracking down the arsenal markings and stamps if you are very interested in them. I had 86 of them at one point, all with something different and cool on them. Great old rifle in my opinion (and i know..everyone has opinions).
