FREE!! Unknown vacuum pumps

So I have these two vacuum pumps that were removed from our shop's air conditioning recovery machines years ago (unknown what brand the machines were) and I can't find any info online it seems. Do the labels give any indications that they'd be suitable? Also, there's four wires...likely two power wires and two switch wires?

I'm not into composites at all, but want to try some small vacuum bagging items like servo covers and canopies, etc, and if they're strong enough, to use with plastic sheet vacuum forming as my tiny shop vac doesn't work too well.

Edited: anyone want these?

Anybody local to SF Bay Area want these two pumps for free?
I really don't intend to ever do vacuum bagging after all, and they've been sitting in the cabinet untouched since getting them.
They're very heavy and I won't ship 'em...hence FREE!

Be sure to change the oil in that vac pump before use or that thing might not run long. Any air conditioning supply house will sell it.

The center (higher) port is your intake or suction port that you would attach to your vacumn bag. The knurled knob is removed to fill the pump with oil.
