Nick Highfield sent me the following letter. I have put the pictures on my Webshots page for him. See
---------------------------------------------------------------------------------------------- Find attached a couple of snaps of the dynamo which I picked up at sodbury for three quid. My first thought was that it had been bodged up out of bits of telephone magneto, but it actually seems rather well made with the frame and bearing plates held together by screws and locating dowels. Still looks GPO to me though, does it ring any bells (ouch!) with you? Nick H.
