Can you help to identify these frames, bikes or parts?

Hi all - I've just (almost) finished refurbing a friend's old frame but got no idea what it is. Not much to go on I'm afraid - pencil thin stays with a huge bottom bracket area.

Any suggestions or tips on what to look for gratefully received.

I think that might be an old viking track frame. maybe.
