Functionality Notes & History:

According to my research this unit is a 1960's vintage comparator based on the monolithic, rounded cast-iron body with the textured finish. Highly likely between 56 - 65 years old. Additionally because the low serial number matching the model name, it originates from the earliest production batches which started in 1960.
