Hi Christopher,
I notice in photos of U-995 there are several shock mounts applied to the inside of the druckkorper between D.Spt that could be where the heating boxes might have once been mounted.
For instance, betweend Sbd. D.Spt 75-76 near the box with the four torpedo lights there is an obvious mount for something about the same size as what we are looking for...
I think, that you are talking about these mountings:
I agree, it matches completely.
and there is another set of mounts similar, below the manual lube-oul pump Sbd. Dspt. 74-75, near the flow meter.
You are talking about this area:
In this case, I think, that lower mountings were for some pipe, which was led there and the parts marked with white arrows are just supports for the shelf with lub oil pump.
I do not think, that Germans would mount control box so low, exposing it for the water splashes from torpedo tubes piping.
There are also mounts that had something removed on the BB side above the flow meter quite near electrical switch boxes.
On the port side I have located following:
and
I think you have mentioned these mountings:
These are a little too large (btw, the electric sockets are post-war in my opinion).
So we have two possible mounting area on the port side and one on the starboard - unfortunately I have no idea, where to look for the second mounting area on the stb.
