I acquired an Allam generator with a Petter AA1 diesel engine some time ago. Dragged it out from it's hiding place in the workshop today, while having a sort out/move around.
I don't know what year it is, but guess around the 1980's.
Details of the genny are as follows.
KVA 2.5. COS 0.8. Serial No. 1022 2P. 110 - 230V. Single phase. Cycles 50. AMPS 17.4 - 8.7.
Made by E.P.Allam & Co. Ltd. Arterial Rd, Eastwood, Leigh-on-Sea. Essex.
The Petter details are... AA1 No74343 AA1. 3 BHP. 3,000 RPM.
Runs and generates like a good 'un. Noisy beast though. Haven't a clue what the excitation socket is for. I'll just leave it to the imagination.
Any ideas of age anyone? Had a bit of a Google, but drew a blank.
