AND THE ANSWER IS........

 

I know I promised the answer yesterday but Life just got in the way...

So here I am with the answer to the " WHAT IS IT?"



This is an    OPISOMETER ......

It is a Nautical milage" calculator" for drafting map scales

The roller on the left side of the photo measures the distances on a map and turns the figures from centimetres (German spelling) to kilometres.

Turning the meter over the instrument figures statute miles...kilometers ...and nautical miles

It also has a mechanical pencil.

I have no idea where we got this antique but we are ready to sell it on eBay.

I am amazed how many there are up for sale at the current time.

Thanks for playing along.

If and when it does sell, I will certainly let all of you know.
