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

any frame number on the bottom bracket?
what is the seatpost diameter?
lugs and headbadge don't point to a raleigh (i think)
also the geometry and lugs look older than 70's to me.
did the forks come with the frame originally???

• No visible frame number - the rattlecan job is pretty thick so it may well be under there somewhere. Might rub the BB base down and have a look if no luck otherwise, but I thought I'd post it up first and see if anyone knew it from the lugs.
  
• Will have a measure in the morning, thanks
  
• I'm inclined to agree on the headbadge, no idea about the lugs
  
• Ace, old school = cool
  
• No idea whatsoever, seller bought it about a year or so ago from a guy that homebuilt it. Didn't mention/know whether it was from frame or f&f though. Will get a shot of the fork crown tomorrow and see if that helps.
  
  
  

Thanks!
