TLS signed “Glenn L. Martin,” two pages, 8.25 x 11, Glenn L. Martin Motors Company letterhead, November 3, 1932. Letter to E. T. Asplundh of Pitcairn Aircraft. In part: “A special design job could be worked out for you, giving you 1400 r.p.m. on the propeller, and if 85 octane fuel were used, 140 H.P. crosses the power curve at 2300 r.p.m….We have just finished a recent contract on the four-cylinder engine for the Army Air Corps, where 120 H.P. was guaranteed at 2100 r.p.m….we had no difficulty in exceeding the horsepower on the motor…The six-cylinder is very smooth at high revolutions, and would also take gears perfectly with some slight amount of re-designing in the front end…The six cylinder engine, however, gets to be a long engine, but this may not interfere with your plans.” In fine condition, with intersecting folds, one vertical fold passing through a single letter of the signature, mild overall toning, and staple holes to the upper left corner.
