Featured English Silver Registration Number & Date Codes Different??!!??

The hallmarks date this brush set to 1928 but the registration number is from about 1937. What gives? Do I go with the later date? Also, is the design enamel or guilloche? The Blue Birds are raised as you can feel their shape. TIA!!

 

DOH! I just answered my own question! I was looking at the mark for London when it's actually Birmingham. The registration and hallmarks match. Sorry

 

BTW, the maker was Charles S. Green & Co, Ltd. This mark was registered in 1904.

Lovely set, Vitry. I do love birdies.

 

Thanks It's the first time I've seen a set like this with birds.

 

My eyes are pretty bad anymore, but I see guilloche engraving under the enamel - the pattern radiating from under the birds. It's a lovely little set...
