I think this might be from the 1950’s, judging from the picture on the back of the other patterns you could buy. I’ve noticed 1940’s male models for knitting patterns always look at the camera. I imagine they were amateurs, as all the young hunks had to join the army. The young hunk on the back page has the far off stare of a professional knitwear model. On the other hand he’s standing in front of an airplane, so perhaps it’s a war time pattern.
Yarn: 3 ply and 4 ply sock yarn
Sizes: Men’s foot size
I have used version A from this pattern to make a lovely pair of socks for Christmas from WYS limited edition fairy lights 4 ply yarn. I used some new to me Addi Crasy Trio needles, which are short like normal double pointed needles, but have a flexible bend in the middle.
