Modernist Designers for Garrard & Co. around 1957? Sterling S&P&Mustard Pot Set  

Those silver hallmarks look like the old school kind that you see in antique silver. Most 20th century silver like the ones from the 1950s will be marked with either just 925 or Sterling or both...I don't know if your set have those markings for effect only to look like 19th century silver or they are actually from that period. Any book on antique silver will have some kind of glossary to aid anyone trying to identify the designer, manufacturer or date when it was produced.

I have only seen examples of Christopher Dresser's work at MoMA in NYC and even though his designs were from the late 19th century, they were ahead of its time, devoid of ornaments, very geometric like Bauhaus and ArtDeco styles of what is to come, the 1920s.

Thanks minimoma

Maybe my photo didn't capture the marks well enough, but it has the squared off Leopard's head mark that started in 1942, and the small "h" from 1957... Garrard still uses traditional marks. I see similar on pieces from Alex Styles made around that time.

I followed up on Dresser because I assumed the person who made the remark knew of a connection between him and Garrard, but haven't come across anything.

I contacted Garrard, hoping they'd be of some assistance, but so far no luck. Really too bad the designer isn't indicated 🙁

Thanks again!
