Loads of gland packing here to be had together with a good memory for which valve does what.
Yes DW you were correct.
It's U 995 ashore for a looksee around. On my list of priorities to do.
First thing I thought of when I saw those valve springs was little half round sections of dried paint going down the pushrods tubes over the camshaft into the sump and thence the oil filters.
But I guess the only way to run this feller up would be to weld a 4/5 inch pipe coupler into the main engine sea suction, get a fire engine water tender round, screw the brass hydrant water fitting into the inlet, run a couple of slave leads up the torpedo tube and off you go.
Forerunner of the control room. Control platform. Don't see any markings on the valves but it appears colour coded port Stb.
