They looked like this gauge for steam boiler:

Well, I'm not sure, if perforated covers of gauge glasses in the control
room of U995 are original, war-time equipment. If you look on this picture
taken during the war: [uboatarchive.net]
(U570 control room), you will see something like steel cover, protecting
the glass only from one side (the side of the glass opposite to the lineal).
I suppose, that perforated covers were installed in U995 control room
while converting U995 into museum-vessel (to protect glass from the visitors).
