The story of acquiring mine goes back to the mid 70s, a time when funds were very minimal. I had seven dollars till payday, the coming Tuesday, and the day was Saturday. I was crossing a vacant lot from my apartment to a fast food place. With proper menu selection, I could have change for Monday. This empty lot was the site of an impromptu craft market on weekends, mostly decorative. At one table, a young guy had only two items. The mixture control bracket and a large, can style Fairchild (with flying horse logo) altimeter. The item asking price was $10 each, but the fellow would not take seven dollars for both although I pointed out none of the lady shoppers would likely buy his stuff. The best I could do was seven for one and as the mixture control would fit on a shelf better, that was my choice. I was hungry by Tuesday.
