ISASC offers this service to provide information on a particular scale such as type, weighing principle, manufacturer's name, period of origin, condition and estimated value.

Note: ISASC does NOT maintain or have access to original scale parts, parts lists, instruction manuals, assembly drawings or calibration procedures for any scale.

Please provide the following:
