I have begun cleaning. I was also told yesterday by its original finder that it came from a cinema in Romsey (probably installed after the, 1936 or 7 I think, regs on stand-by lighting.
The base tank with 95% paint, has a part number of 41170 ABC. 41170 is a lateish part number and I have never before seen an alpha suffix other that VF/VA/VZ/VZA etc.
I'm wondering if it was a special for Associated British Cinemas??

thoughts anyone

Roland

Some progress.
The dynamo is back together and, with nothing else connected, spun over with rope gives nearly 3 volts which is very positive. The biggest job was cleaning decades of goo from inside the dynamo casing. In places it was over 1/2" thick and completely blocked the dynamo's drain. I suspect that is an indicator of the state of the engine :-(
Incidentally I was wrong to think it compound wound as its plainly shunt. GEC also marked each lead with their usual letters: A, AA; Z, ZZ and Y, YY.

cheers
Roland
