IL-4 gauges
 

Anyone have any idea what these two instruments are for?

As far as I can tell, they don't do anything, though they look as if they were made with animated needles, and were perhaps intended to.

They are engine air intake temperature gauges.

Thanks.

Probably not practical to make them work, and without icing modelled, not likely to be much use anyway.
