Thanks guys for your pointers...unfortunately these links I've already found. They're all to do with the small "cube" generators that seem to be everywhere - this is the big brother/cousin of it as a 2KVA power-source. The main body of the generator with the end casting attached I can just about lift solo....that's a totally empty casing. Fully assembled it's a two man struggle...or a four man comfortable lift - it's the main reason I didn't pass this one by......it's undoubtedly WWII German.......but a rare beast. The engine is a 125CC engine I believe Datrus. If you can find even the smallest picture of one in service.....or find a link to one somewhere..........i'd be extremely grateful for it.
