Beach Calculating Machine

Description
This small black machine sits on an iron base with four short legs. Seven toothed semicircular discs, mounted on a single shaft, are used to enter numbers. Between the toothed discs are full discs with the digits from 0 to 9 marked around the edge of each disc 3 times. The face of the machine is a steeply sloped curve with a rounded top. The toothed discs protrude from slots in the face, and one digit on each disc is visible through a window. The handle is on the right side. Several parts of the machine are missing.
The machine is marked on the front: THE (/) BEACH (/) CALCULATING (/) MACHINE. It is stamped on the bottom: 2151. A mark scratched on the bottom reads: Geo. J.
The Beach calculating machine was manufactured, at least initially, by the Book-Keeper Publishing Company of Detroit, Michigan. The firm had previously manufactured a two-wheeled stylus-operated adding machine on the design of Lester C. Smith (a modification of the Webb adder), but discontinued this product after a patent dispute.
