The stuff sold in the 80s was definitely identical to Shamrock (and sometimes
Brentwood or Emerald or other similar brands) and had the same 3-color tabs.
031 was 1.5 mil, 041 was 1 mil, and the .5 mil stuff was either 051 or 061
(don't have a reel handy to check). The numbers were the same whether it was
back-coated or not, brown oxide or black.
