I seem to recall that at least two of the senior members have extensive collections of old NEC, handbooks and even pre-NEC guides and codes. Maybe one of them recalls the queens breaker or can find it in an index?
If NFPA was always headquartered in the northeast, I could see earlier editions using more slang and especially from that region since it's origins were there, confusion likely resulted when someone did not know what the slang meant though. The past 40 years or so they have tried real hard to not use any kind of slang
Well if we need to disregard 100+ year old information then we have a lot of basic theory we need to throw out, and this goes for direct electrical as well as other related physics

That makes sense to me. I know I've seen old Siemens /ITE literature on electrical equipment where the devices we now call "Circuit Breakers" where originally called "AUTOMATIC Circuit Breakers" when ITE released them (for those who don't know, ITE stood for "Inverse Time Element", the basis of thermal trip units used in all CBs and most thermal OLs for decades, until electronics started to displace them recently). I don't know when the "Atomatic" was dropped and switches became just switches, but I'd be willing to bet it was some time shortly after everyone else jumped on the ITE bandwagon to make "Automatic" circuit breakers. It's likely that once everyone was selling them, it would become confusing to have two totally different types of devices with similar names.
