The 2001 version of the GB/CB/1910 specification

I drew a sketch of the GB/CB/1910 specification on August 31, 2001 that was trying to be appropriate for the ship as upgraded circa 1917. I showed the upper and lower belt lengths and put 8-6in QF guns in casemates, rather that the twin 4in mounts of the 1971 sketch design. I realized that I had omitted the torpedo bulkhead, and putting in required changing the machinery to 1913 weight standards. This is the Springsharp report:
