New toy - lovely little Villiers gas-fuelled engine with red cowl and pull-start connected to an Erskine 24V DC generator. The ensemble in a skid of square-section tubing, all painted battleship grey. It is nearly pristine and hasn't got many hours - the oil is clean and clear!
The engine is S/N 27557 and Type C12.21.01, the generator is S/N 48058, Type GR 24 V, producing .55KW at 3000 rpm, 24.1V, 22.5A. It has a small distribution panel with ammeter and four round two-round-pin sockets. Looks military to me, as the spark plug lead and plug are shielded and shrouded respectively.
Anyone have any idea who and what it was for? If it was a charging set, the voltage seems a bit low for 24V batteries and kind of high for 12V. Standby lighting?
