Cenco Laboratory Weights Essay (Catalog J-150, 1950))

The scanned pages are from the Central Scientific Company catalog J-150. The pages are in order going from left to right. Clicking on the icons will bring up an enlarged image. Note that the Class S-2 was replaced by Class P in Circular 547 of the NBS released in 1954, so Class S-2 weights are made prior to this 1954 change.
