McElroy Stream Keys:
"First Model" Streamkey
This a chrome very early McElroy Stream Key. According to Tom French at Artifax Books, this is probably a late "first model" Streamkey, made around 1940 when McElroy ran out of the triangular nameplates and decided that decals were less expensive. This variation is scarcer than those with the metal nameplate. Like all Stream Keys, the shorting lever curves inward, rather than outward like most other keys.
