Warren63 wroteHi folks. I’ve just bought this large Alex Adam safe plaque and wondered what the 267 on the top of the plaque signifies. Is it the same as the Millers plaques with the 212 relating to the fireproof properties of the filling inside the cavities ?
Hello again Warren63.
The only reference that I can find to the number 267 is in connection to distillation temperatures in a very technical NASA publication a section of which I will attach.
The Coat of Arms of Falkirk includes translations if the scroll inscriptions which you may (or not) find interesting.

You will find some Adam family detail in Grace’s Guide. Lovely plate.
