Default Need help to ID Generator

This generator was on a 6 hp Petter AVA1T NO.3129011 diesel. It has 4 slip rings and a wide commutator with 2 rows of 4 brushes placed all the way around and staggered.

Looks like four pole, so 1800 rpm for 60 cycles.

Commutator means self excited, and possibly exciter cranked as well.

Four collector rings could mean single phase reconnectable between 120 or 120/240, OR, 120/208, three phase, OR 120/240, three phase. . Or for that matter 277/480, or almost anything else.

Thanks for the replies. It does have the name Stamford on the plate of the whole unit, and dose crank when I put 24 volts to the solenoid in the control box but gen wouldn't put out any power. I would like to find a wiring diagram.

Thank Allan for the links. One of those gens looks like it's from the same manufacturer but a different model. Here of what I assume is a voltage regulator and one of the wires was broken off the pull-down coil. There was a broken spring on one of the slip ring brushes. A friend gave me this set more than 20 years ago and I got it running, used it to build a house then it quit making power. Then I left with another friend to have a look at. He covered it with a tarp and there it sat for 20 years. I even forgot I had it. So now after being on Smokstak for a few years, I thought I'd take a look at it

I think it might be a BKB generator built in Birmingham UK in the 70s
