Nice American Assay scale. No maker label, so I am not sure about the maker !

The scale is from unusual small size

12.3" wide
13" tall and 5.7" deep

A little wheel on the front take the beam in and out of the weighing position. The little knob to the left move the both stopper for the pans up and down 

Found that nice scale on ebay...
but toke not enough care with my
bidding ! One of the hangers is not
original or from a other scale....

Again a expensive lesson !!!!
