Help with makers mark please

Hi All, can anyone please help identifying the makers mark on this bracelet?

There is no comprehensive published reference for 20th century London makers’ marks. The London Assay Office may tell you - contact them via their web site. If you do contact them and get an answer it would be very useful if you could update this topic for us.


The London Essay office did contact me back to day that the makers mark was a private maker anx they did not have permission to give the name out. ?

Thanks very much for letting us know. I guess the Data Protection Act helps in many cases but the consequences can be frustrating!
