Smoke free Antique collector. Unfortunately I’m not knowledgeable on this but please message any questions before you purchase and I’ll do my best to answer. Not really sure what the bag is used for specifically but reminds me of a bowling bag.. it’s impossible to find any info on this bag anywhere.. I believe the bag is canvas and The Berlin feels like felt or velvet. Could use a cleaning but I don’t see anything too bad but there is some stains and blemishes but I could be missing something.. so please view photos closely. I believe to be 60s or 70s Thanks for looking!
