From trawling through this forum I've seen, Schneiderman, that you are wanting a copy of the full document. Did you manage to locate one? I'm not sure if the RAF Museum has a copy among its HP files, might be worth checking if you haven't already.
Its discussed in Tony Buttler's Fighters and Bombers 1935-1950
I wrote an article a few years back about the development of the high speed bomber concept, incorporating Volkert's paper, the Blackburn B.28 and the Mosquito and referenced the book, of which I have a copy. A paragraph:
"One of its eager supporters was Research Director Aircraft, Capt R.N. Liptrot, who calculated that such a machine's top speed could exceed that of the Supermarine Spitfire, at that time still in prototype form. His response to Volkert's paper was deliberately provocative, designed to ensure vigorous argument. Another supporter of the idea was C-in-C Bomber Command, Sir Edgar Ludlow-Hewitt, who noted that; “...it is not an unarmed bomber that we require, but a S
peed Bomber.”
Among the high level discussion within the RAF that went on over the winter of 1938/39, the Chiefs of Air Staff agreed that a formal specification should be written and prototypes built. Despite this however, the Operational Requirements department declared that the 'Speed Bomber' enjoyed no significant benefit over contemporary concepts. By August 1939, a few weeks before the outbreak of war, Ludlow-Hewitt again voiced his support for a fast bomber, insisting that it should be given the highest priority. This was effectively countered by Assistant Chief of Air Staff William Sholto Douglas, who was against the idea of an unarmed bomber, claiming that it would be countered by improvements in single-seat fighters in due course, although simultaneously he authorised construction of a prototype of an unarmed reconnaissance bomber concept under development by Blackburn Aircraft in Yorkshire."
