Names and faces to bikes

Cheers! I didn't restore the frame myself, bought it off the bay freshly re-painted and built it up slowly whilst bed-ridden after a nasty crash last year.

Nice bike, I've got a Carlton from the same year. Couple of questions -

What size seatpost did you use ?
Is the headset standard 1" threaded ? I know Carlton and later Raleigh used a non standard tpi at various times
