Sorry, I perhaps should have realised you'd need to know this!!
The needle size is 2.5 or 3 and the wool is 4 ply. The guage does not say any more than : Tension: (Guage) 30sts = 10cm!
The pattern is a lot in stocking stitch but also uses a pattern of 1st row: k2,p2, 2nd row: purl, 3rd row: p2,k2, 4th row: purl.
Hope this is enough to get me an answer.
