4-needle sock pattern?

We had to knit a pair of yellow wool socks on 4 needles in primary school, late 1940s. I remember taking mine home for my aunt to turn the heel! I've a 90 year old friend who is an excellent knitter, sometimes wears self-knitted socks. I'll ask her.

If you come across any 4 needle ones with the old fashioned heel turning could you send me a link please? I have been looking for one of those for ages. Most patterns now do a funny sort of square heel but I think the heel turning sort is neater. Lots of sock wool about nowadays. Most of the socks OH wears I have knitted him.

Someone has just given me a book of sock patterns (looks a bit daunting)

Do Ravelry have any free ones?
