AGA's signal manufacturing division became Signal Service Corp. in the early 30's (right guys?), then Marbelite took over SSC in 1945 (announced in a printed ad). AGA designs go back to the 20's.
Marbelite took over Horni in 1947, also announced in a printed ad.
The thing is, it seems all these companies, and more, shared lots of designs of various things. The progression of designs from one company to another is not an easy, smooth line. I think Ruleta, GE, Highway Sign and Signal, and perhaps others, are all intertwined with Marbelite/Horni/AGA in one way or another.
What's REALLY cool to me is that present-day company GTE still makes 8" signals with the same basic housing design that Marbelite was making in the 70's...and that housing shape goes way back to Horni signal in the late 30's, though it has been modified/modernized over the decades. I was excited to see some of the molds at the factory when I visited there last year - like I was seeing something sacred. There was even an old Marbelite LPS-20 housing among the random bits in the yard - obviously, GTE acquired Marbelite's stock and molds when the company was formed...they just didn't get the name "Marbelite".
Larry Rogak mentioned on FB that he spoke to a Marbelite employee a long time ago, who claimed a few of these companies were run by the same people.
