Papaw,
+1 what bonneyman said.
It is a very handy saw when your up against confined spaces. Depending on what you do, this might be something that could be used a lot.
That said, most folks, including myself, can get by with a standard hacksaw and can go their whole life without needing a close quarters saw.
So I'm guessing the market for a close quarters hacksaw is likely to be relatively small. Of course, I could be wrong.
At any rate Papaw, I'm sure you will make out just fine in finding a new home for this unique vintage Crafty hacksaw; happy prospecting.
