The version of the pattern on Knitting-and.com has been modernised, corrected, charted and checked for errors using a stitch map.

The original version writes all ssk and k2tog as “narrow”, leaving the decision of which one to use to the knitter.
It also writes slip 1, k2tog, psso as “slip 1, narrow”, without including the psso.
Even rows 14 - 72 are also not written out.
