For sale is a fascinating piece of NASA history, 6 module assembly diodes. One of the diodes bears a NASA stamped tag along with NASA-stamped configuration requirements data list. The tag identifies the part as a Module Assy Diode for the Skylab program. The GE0077 Serial number on the tag exactly matches the serial number on the diode itself. It’s listed quality test date is March 8, 1971. The lot contains 5 other diodes whose history is mostly unknown, though two of the have labels with a testing date, one tested on Feb. 7, 1973 and the other on July 29, 1965. This is from the estate of the Launch Support Lead for Apollo and Ground Systems who worked for General Electric. Based on estate items, he had a strong background in electrical and computer engineering and a longtime association with General Electric, part of their Quarter Century Club. Picture 12 is a letter of his to the launch support team, dated Nov. 14, 1973: The Subject Line reads: SKYLAB-4/AS-208 LAUNCH SUPPORT. I have several items from the estate that date well before 1973, but I can verify he was the Launch Support Lead in 1973, whatever role he had with earlier Saturn V missions. The original letter itself is not included in the sale, but I will send a copy of the letter with the parts. I want both us to come out winners here. All of these items are from a smoke-free home.
