All About Pocket Knives

Just picked up an old 1970 (10 dot) with the pattern number "087H". Based on Case website, it is a medium three blade stockman with black composition handles( dense fiber of some sort). Does anyone know what the "H" stands for?

Thanks in advance.

should be 087HP (sheep and spey) or 087HE (sheep and pen blade)

Thanks Mustkrat Man. I knew I had seen those letters on knives before but did not remember what they stood for. This is a little weird. It only has "087H", not other letter after the "H".
Thanks again,
Nifenut
