Most pawn shops are in business to make money. I doubt it that they have a Buska that they don't know what it is.if their not sure about something most get it authenticated. What you are probably seeing is a good knock off.
I've certainly seen far crazier things after 14 years in the collectibles business than a pawn shop owner selling an unmarked pool cue far below value. And I wouldn't expect a pawn shop owner to necessarily know where to go for verification on an item like an unmarked cue, Google and eBay is no help. It wasn't that long ago we saw the eBay store guy selling an unused Tad and unused Gina, both from the 60s, for the value of the Brunswick cases, which he was familiar with. The Gina was described as having "some girl's name on it".
Anyway to the OP. Strongly believe its a Bushka? Send it to Tascarella and take the guesswork out of it.
