Hi,
I can't be of much help, other than to suggest that, if this is the same John Gilbert as that of the John Gilbert & Co. Ltd., and I presume it is, then they were a very large outfit and probably used more than one makers' mark.
They were listed as silversmiths and electroplaters in 1865 at Ryland Street North, Birmingham. They had a London office at Ely Place, Holborn. They had become a limited liability company by 1880, and are known to have produced a great variety of wares.
There may have been a connection with Thomas Prime & Son as they appeared to have shared the same address for their Birmingham offices at 107, Ryland Street.
At the moment the online database of makers' marks at the Birmingham Assay Office only covers the period up until 1858.
