I think you are correct for Guildite in 1933. Staybrite was registered in 1928 from what I have read (used for tableware originally) but was also registered in the US and Canada. The tradmark and the patenting in the US was somewhat confused due to independent developments in the metal alloys with US based companies. Convoluted to say the least.... but likely the requirement that those using Firth made stainless in the US also could mark it with the name. I don't read that it was required.

There are examples of Guildite and Staybrite marked cases.... here is one: at WUS forums But the markings are difficult to read.... believing the OPs read.

Anyway.... Very cool stuff to see.



All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
