A very short lived N.E round that was once considered by the Brits as a military round in .26, .33 and the lesser or rarer .40 BSA round.
I think they were in production for only a very short period 1921 - 1923 (AFAIK) with as far as munition production goes, this being a full packet of Kynoch .33 BSA with 10 rounds it was not a very ballistically efficient round.
This is probably a jewel of my collection of packeted ammo being so rare and in pristine condition, I do have a single in the N.E collection I'll find a pic of it and post but this is something not often seen at the time of purchase there were 2 packets offered up but I could only afford one at that juncture.
.33 is the middle one of the 5 N.E's not sure the paper patched maybe a 500/450. (Not the best pic but its all I could find)
