and can't find any info on

Model 344

Hello, Sudsy. I looked at a couple catalogs, all that I could find was a Proto 345 Low Clearance Adjustable Height Hacksaw. Looks like yours is a fixed height, so I would call that a Low Clearance, or, Close Quarters, Hacksaw. Regards, Lou

I think I have a couple of them just like that. I'm not sure of the model no.

I've never seen that style of hacksaw either. Very cool.
