Antique Howe Scale, early - I think this is the same scale that was in my Uncle Deck's (Rice) General and Grocery Store in Doyon. It fascinated me as a child. They even weighed and sold oreos by the pound before all the cellophane and plastic packaging.
The Front has a Postage Scale label with its weight measures and rates in the front. It is marked Crescent Postal Scale and has a date of January 31st 1899 in the lower right hand corner. There is some earlier dates to the left but this is the latest one. The mechanism was made by Crescent but the Acid Etched Pattern and metal along with the Patina was done by Tiffany Studios.
