Item details

This pre-WWII geared 10" Precision proportional divider, made in Germany and marked J. Diamant, is is very good condition and comes in its original pin-lock case.

True, the divider could use some polishing, but the thumbscrews work easily, and it can be adjusted as it was meant to be adjusted in order to function. The case is worn and ragged in areas as shown by the photos; the interior velvet lining is discolored and there are a couple of rust spots, as the pins used to lock the case closed are rusted.

This item will be shipped with the US for free and will be insured. Please check my shop policies before purchasing.
