These aren't uncommon in eastern Europe. I seem to recall they often cracked like that.
The whole shebang is apparently $75. When I posted this thread earlier, the price was $99. Not my ad, by the way.that's an FPU vise. I'm pretty sure they are made in Poland. I'm sure the experts here can give you more information than I have. If it was cheap enough i'd buy it for sure!
It reminded me of a Gressel I saw some in an old youtube restoration video. It's an interesting format. Not sure how useful it is for larger workpieces to make the outboard jaw static, but I've been keen on taking that design for a spin.These aren't uncommon in eastern Europe.

This Polish style is inverted when compared to the German style dovetail vises (leinen, schlegel, gressel...). On those, the rear jaw would go inside the base instead of hugging it. This Polish style may make the guides and the lead screw less exposed, and also made to incorporate a swivel underneath while the classic German design fixed to the end of a table. But most likely the polish cast iron wasn't very high quality so a lot of them cracked like that.
That’s a genuine FPU, made in Poland. Look at the emblem. That’s the mark of the real deal. They are great vises. Even with the cracked off piece, it could still be useful.Bison vises are similar (The US branch of FPU?). For a few $$, that one should be fine for most uses.
I have a 5" version, not sure if its a real FPU, Bison, or knockoff

I was referring to mine being real. Many layers of paint on it, so can’t read a logo.That’s a genuine FPU, made in Poland. Look at the emblem. That’s the mark of the real deal. They are great vises. Even with the cracked off piece, it could still be useful.
Sounds like a LOT of paint. Good luck with the uncovering whenever you get around to that job.I was referring to mine being real. Many layers of paint on it, so can’t read a logo.


Where are the 3 locking adjustment screws?
Thanks. I don’t know they were one side only.^^^ other side
I have a Schlegel of that design with no adjustable gib, so no bolts on either side.Thanks. I don’t know they were one side only.
BTW, FPU stands for
Fabryka Przyrazow Uchwytow
It turns out that one of the only Polish words I can pronounce is piwo (beer). So, I'll just keep pronouncing the name as FPU. Phonetically, that's "eff pee you". Hmm. . . Pines may have something to say about the name.Thanks. I don’t know they were one side only.

I wouldn't say never. I've found two people that have the vise but both of them are cracked along the dovetail so I;m hoping they would consider parting them out. They both have the gib I need so I'm still hoping.You'll never find an oem gib.
