Hi Nick,
Does your ARC-57 have any manufacturer information on it? My one and only sighting of a B-58 in flight was one afternoon, looking South from my bedroom ina suburb just North of Buffalo, NY. It was circling low and slow (well, relatively) over North Buffalo. I do not know whether I knew at the time that Sylvania had a military electronics group located in the old Pierce Arrow building complex which was located at Elmwood and Great Arrow. I found out about that group in 1962 when I earned some extra money writing a radio mesh network analysis program for the IBM 1620 we had at the Univof Buffalo Computing Center. Werll, they didn't use the term mesh network but that's what it was.
