Santa Fe 4-8-4 3751 has a Golden Glow headlight mounted up front. I've read that Golden Glow only made the reflectors, but this headlight appears to have been produced by Golden Glow, complete with the name cast in the side plate, along with the word ESSCO and PHILA (Philadelphia, of course) along with a Keystone logo at the top. And, of course, that distinctive yellow color when illuminated.
