Default 1956 Onan 3MDSP 32VDC Genset Restoration

So here we have a 3MDSP-232R/1A built in June 1956 that was restored 15-20 years ago. Still waiting on some more details on the history but near as I can tell the restoration was done by one of the Onan guys at Cummins Northwest in Seattle.

It sat in the lobby for many years before ending up stored in their warehouse until last year. The Seattle location has been moved to a new facilty in Sumner, WA and the 3MDSP is out of storage and on display in the lobby once again.

I'll start off with a couple pics of a different 3MDSP that more or less is what this one looked like prior to restoration.

OK, 32VDC Onan Marine genset/battery charger here we go!

Nice! When I first looked at it I thought it was a moonshine still with all that copper tubing polished nice and brite. Now I'm thirsty.

Make a real nice addition to a battery/inverter backup power system
Be a shame to just let it sit around, looking pretty

I have a air cooled version of this. I need a piston and rings. It was a really neat running rig.
