How do these work???

[Millietant]

I've got an even older set in my garage that were in my gran's house when she died 30 years ago.

A tray on one side and a frame on the other side (with 2 pans of different sizes which fit) but no scale, just a pointer with a middle marker and a whole boat-load of small weights.


If you want to weigh out 8 ounces, you put 8 ounces of weights on the tray and then fill up the pan until the pointer comes to the centre mark - eg, both sides are balanced, and you have 8 ounces in the pan.


I remember shops having and still using these in the early '60's
