Cheers Moose. Looks like it is the 616 engine as the engine number starts with 616.
I trie Manfred P already plus plenty of others. This I have finally found a set. Almost 400 euro though!Hopefully this will be the last piece of jigsaw for motoring. I can get another 616 engine from a car for the same price. The clutch may be a problem joining up and also wouldn't know its history. Thanks for responding.
