thanks Pascal. Unfortunatelly i did not found images of instruments for this submarine of WW1. So i made them with a little "retro" style.
As for the altimeter i saw that the indicator does not stop in the depth of 100m, but keeps on turning around. So i make a new instrument adding an indicator for 100m and a numeric panel

here it

100m of depth
