Production of the A-4 flight suit began in the 1931 fiscal year and ended in 1943. This A-4 suit is from the first order in 1930 (1931 fiscal year) made by H D. Lee Inc under the 31-297P order. I don't have any information on the quantities ordered, but as the Air Corps was small then perhaps no more than 2,000. It is tagged a size 44. It has features not seen on later versions, such as two knee pockets, a leather hanging strap and a separated fly. The zips are size 5 Talons with Hookless stamped on the puller in smaller letters. The zips have a 1925 patent on the other side of the pullers. It is in remarkable condition for its age, having a couple of repairs and evidence of paint splashes. Written on the name strip is D.L. Hutchins. I have researched him and discovered he was born in 1895/6 and died in 1972 at the age of 77. He most likely joined the AC after WW1, probably sometime in the 192os and was a major in 1937 when he undertook a year's course at the Industrial College of the Armed Forces. In November 1944 he was appointed Commanding Officer for Base Air Depot No. 2 at Warton, England, holding the rank of full bird colonel. The suit still retains his colonel rank insignia. If anyone knows anymore about Hutchins please let me know.
