† Rod number is a two-digit designation of the largest (first digit) and smallest (second digit) rod sizes, in eighths
of an inch. For example, a 65 rod is a two-way taper of 6/8" and 5/8" rods. An 86 is a three-way taper of 8/8", 7/8",
and 6/8" rods.

†† Pump type is indicated as follows:
     RH = heavy-walled rod insert pump
     RW = thin-walled rod insert pump
     TH = heavy-walled tubing pump
