Notes: "There is no information on when this style of 4236 planimeter was made. The white-on-black markings on the tracing wheel, vernier, and multiplier disc are unusual. The best estimate for a date is mid 1950's, as the next iteration had a closed-top design, with the tracing wheel protected from dust and dirt."
