Vendor Catalog Scans 1940-1980

The images and catalog descriptions are scanned from catalogs in the curator's collection. In each case an effort has been made to scan all of the balances of a given manufacturer in the catalog. It should be noted. however, that the distributors generally show only a selection of balances from any one manufacturer. Catalogs are selected from the curator's collection at approximately ten year intervals, when available, with a second criteria being representation of the specific manufacturer.
