McInnes Dobbie Steam Engine Indicator Boxed

This is original and comes in its orig box with spring fittings, slide ruler scales and bits and pieces. Looks brass and complete apart from 2 small fittings are missing. These are used to test the condition of the cylinder pressure in steam engines and traction engines. A very cool old thing.

Condition looks very good, not sure if it works tho. Looks old.

$9 postage NZ wide. I can group post one or more items for the postage cost of the first item.
