Can-fed ink feed. "Sprayset" — sheet is sprayed with ink setting solution when the delivery tray is returned to the left. Bed adjustable within .240" range. Automatic short travel cylinder trip, "making it unnecessary to travel the cylinder the full length of the bed when proving forms up to 14" long. The full 21" printing length can be obtained by merely traveling the cylinder to the end of the bed" (this sounds like you don't have to adjust a cam). The tray at the right end is for washing rollers. There is a niche in the bed for a plunger solvent can.

SP stands for Simple Precision and was "a low priced precision test press" series (1968 Vandercook catalog). Sometimes they used a hyphen between SP and the number, and sometimes they didn't.
