Information about this blue twin tank air compressor

It’s a blue twin air tank air compressor with 6.25 Kohler K141T engine. Specs: 29357d.

Runs great, but has rust spots.

It is the cast iron series and rather heavy. Serial number 5071582.

What do I have here? Can’t seem to find anything about it on the internet but a manual for the engine. Thank you for your time.

Respectfully,

Drew
