Description
This wooden model is associated with inventor James Powers. It is roughly the shape of a trapezoid, with a curved and notched bottom edge. It may be a pattern used to make a mold, which in turn were used to make pieces of this shape. The phrase "one off" indicates that one piece of the given shape is to be made. The phrase "hard compo" suggests that it was to be made from a hard composition plastic. The number on the pattern does not match up with the numbers of the parts of Powers tabulating equipment shown in 1992.3214.03.
