4oz vintage 3ply 100% wool yarn in beautiful bright blue (Harley Shute TN38)

Here are four balls of vintage Emu Scotch 3ply 100% wool yarn - in a beautiful bright shade of blue. Each ball is 1oz / 28.35g and you’ll need a little ingenuity to match it up with modern knitting instructions as no tension or needle size is given but it looks like a fine/fingering weight to me.
