Probably from the late 80's 

All belting leather trim in mostly decent shape except for one spot on the top saddle.

All Belting leather shoulder strap,original top hook.

Leather front straps and clips,Side buckels,zippers are all functional.

Does include a lock but no key for it.

Nylon interior does show wear and tear but overall clean and classic.

I believe this was the 48" length but I will double check measurements.
