This is a very nice example of some travelling diamond weighing scales housed in a mahogany box by W & T Avery, Birmingham.
It has the hanging beam with the two hemispherical brass pans. There is a lidded mahogany compartment which houses the complete set of eight carat weights. The larger brass weights are circular, and the smaller ones are square tapering weights. Lovely to have a full set of weights.
On the inside of the lid is the original label inscribed ‘ A table by which may be calculated the value of any weight of diamonds’. Made and sold by W & T Avery scale makers Birmingham.
There is a slot on the outside of the box where the original brass tweezers are housed.
The octagonal mahogany box measures 14cm w x 7cm d x 3cm h.
