The gauge on the left is for compartment pressure and reads 0-600 foot,
0-266.29 lbs. It just has small holes around the circumference, and no nipple for a gauge line.
We need one compartment pressure gauge for the Conning Tower. We need two 0-600 depth gauges, one for the Conning Tower and one for the After Torpedo Toom. We would also like to find a third set for use in the USS Roncador Conning Tower.
If we found the correct gauge bodies and tubes we can replicate the needed dials (faces).
We also need the sea and vent valves for both After Torpedo Room and Conning Tower.
