I have been looking for a good while for a rucksack I used to have in the late sixties and early seventies. It was green canvas with two pockets on the front. Leather trim and buckle straps.. A drawstring and flap. There was no rigid carrying system but the back straps came out of a leather patch on the back which had a metal ring that the straps attached to. One strap had a buckle and the other a hook that went into a metal ring. Can anyone tell me what it's called or have one for sale? I'm trying to get a retro kit together and I have everything except the rucksack. I've searched everywhere but can't find what I'm looking for anywhere. I know they would be pretty rare now but I have some cash saved ready to buy. Any help would be appreciated even if it's only to tell me where to look. Thanks.
