(See my other lab weight auctions too)

My reference #51

Manu: Computing Scale Company Dayton Ohio USA

Model:  1oz calbration weight

Condition:  On a scale of poor/fair/good/excellent it's in the fair range.   I got  1oz on my lab scale see the photo. That seems to indicate it's about +-.01ounce accurate (my estimate)

Cosmetically it's fair.  There is some corrosion there are some touched up spots.

Regards,

Paul
