Saving Old Seagulls

What is this, a hybrid? There were some 102cc motors in the 1940s with the ED lettering, but this looks more like a late model.

Hmm. There were a few very late batches of 102s made up for dealers to offer as a 'bargain basement' motor.

This one - I just don't know! It would be interesting to see the attchment of the petrol tank to the block..
