I have just aquired a load of old 1960 pattern combat jackets and in amongst them is an olive green parka with a furry type of non detachable lining. It has no hood or collar but has button holes around the neck for a detachable hood (not present). Can any of you old sweats tell me anything about it, what year it was introduced etc. There are no labels in it apart from a green one on the neck but the writing is illegible. I am assuming it is an old British Army issue because it was in with the jackets.
