My first impression is that this belongs to a European safe and is probably the secondary plate showing
only the classification.
The design strikes a 19th century note similar to that on the attachment. British safes of the period carried no
classifications for fire or burglary until after the last war. Tested fire protection in the UK only came about when UL tested
Library Bureau fire-files and cabinets started coming in from the US. (Chubb RP Cabts. and files for instance)
Burglary grading on British safes was only undertaken well after the war when export markets were being sought and
the actual testing and grading carried out by the respective test houses in Europe, Scandinavia, and the United States.
The first British testing and certification body was established by the LPCB at the Fire Research Laboratories in Borehamwood
in 1992 in the same premises where the FOC fire tests had previously been conducted.
