A scale ... for what ?

[fernando]

Thank you again, Richard
I peefectly understand what you mean; quite simple and ingenious, revealing a wide functionality to this device.
However, the counterweight shaft is not threaded and the 'ball' is not so tightly secured, in that, once slightly moved out it falls off, not standing the minimum adjustment. So it either suffers from wear or the explanation would be another one.
Still i appreciate your reasoning.

Hi Fernando,

This interesting item kept me thinking and after reading your last post i thoughed about someting. The ball can be taken out (shaft and all)?
Maybe there used to be more than one ball with shaft of different weights?
There is enough room in the box left for other weights as well.

The counterweight shaft is not removeable, Marcus; it belongs in the scale arm.
The shaft length is precisely that to lodge the present ball ... no less, no more.
