The 'Staybrite' mark is interesting....
Quote:
Staybrite steel was made by Thomas Firth John Brown Ltd. of Sheffield and was protected by Swiss patent No. 138 647. Use of the name Staybrite like this required permission from Firth, and it could only be put onto items that were actually made of Staybrite steel.

Different watch and markings, but I've an example that is also marked Staybrite.... I also presume this is pre-Guildite other wise it would be marked in addition.


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
