Mystery Object No.119

Recommended Posts

He is winding the handle which is attached to a spur gear in the round housing on his belt, this spins a flywheel attached to the flexible drive going to the sprocket driven straps around his boot. These pull the polishing cloth(seen appearing from under the sole) around and around his boot in order to keep a good shine on them in off road situations, and a spiffing good job it does too.

 

Later versions had two coupled contra rotating devices but were rather tiring to operate........:coffee:

Pre GPS a person powered Gyro compass.

 

Yes Tony well done, is that a first time for you as well?

 

It is a ManCAN (Man-Carried Auto Navigator).

 

Foot powered by puffs of air. The fluidic navigation device then tracks the direction & distance travelled by the soldier from a known point. "Three simple adjustments are all that are required to permit the operator to determine his position accurately in dense jungle".

is it a Sperry design? Has their look about it.

 

It's not actually a Gyro, but it seemed too pedantic to dismiss your overall answer which was pretty much there. This fluid navigation device, which I find hard to see how it remains accurate, was made by Martin Co.
