Can anybody help me find who makes this lighter?

My grandfather used to smoke cigars and he gave me this lighter when I started smoking cigars, unfortunately it seems to have a leak in the base by the valve. I don't know anything about lighters, but I'm guessing / hoping that it's just a piece of rubber that's gotten old and brittle that's the problem. Either way I talked to cigar aficionado who told me that whoever had made this lighter had essentially forged their logo and that they couldn't help because the lighter was never connected to them. Does any body know where this lighter might have come from? It would mean a lot to me if I could get it fixed.

Thank you
