Model Associated with an Invention of James Powers, #311


This wooden model is associated with inventor James Powers. It has projections at the two sides (one broken off) and at the bottom, as well as a piece painted black at the top. It may be a patterns used to make a mold, which in turn was used to make pieces of this shape. The phrase "one off" indicates that one piece of a given shape is to be made. The phrase "hard compo" suggests that the piece 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 James Powers tabulating equipment shown in 1992.3214.03.
