Old Tool :Has me stumped:

[Lafitte Deux]

Trying to ID this for a friend who found it an old garage.

It's approx. 14" wide by 10" tall.
It has 3 clamps at the base which move in or out.
The center rod can be turned by the handle at the top.
Appears to be home-made because of the welds.

We're just curious about what it's purpose is.
Thanks for any help or ideas!

Looks like a jig for metal sheet, and it kinds of reminds me of a spot welder set up.

Jig to align two ends of a bandsaw blade for brazing.

Looks like a one off something Some kind of a special purpose press. I'm guessing the outer clamps are to hold the center of what ever piece you'd be working on .

I'm thinking pin press or riveter.

Maybe an off shoot to an arbor press

looks like an old pop rivet tool, i have a similar one for the rivets on my tractor brake shoes

It could be for pop rivets, but the handle rod isn't threaded.
