A 'Noiseless Remington' typewriter

Churchill was a severe taskmaster, frequently obliging his personal secretaries and typists to work well past midnight.  As a result Churchill’s secretaries did not bother with shorthand note taking and typed straight from the Prime Minister’s dictation.  This might reasonably explain his infamous dislike of the noise of typewriters which led to the custom-made ‘silent’ typewriters, examples of which were kept at all of his regular working locations.
