Warren63 wroteI actually bought some plaques privately off a bloke selling a collection he’d acquired, and I specifically remember seeing the two parts separately. Not being a collector he had no reason to associate them together, and myself not knowing either again thought it was a European piece. Thanks for your info and time Tom. I appreciate your efforts hunting them out and explaining.
The Royal Crest was used by quite a number of safemakers in Victorian times without any justification (apart from Chubb) and purely for self aggrandisement and which would now be totally unlawful.
The Tann version mentioned would have allowed the crest to be attached above the basic Reliance plate in special cases which mainly appear to have been when exported to the Antipodes.
A much more appropriate and lawful Crest for a London safemaker would have been as on the attached which is the crest of the City of London.
