Dating pieces of EPNS

I have two lovely pieces of EPNS. I have identified one as Israel Sigmund Greenberg and the other as Cooper Brothers (thanks to this forum) but I would like to try and date them and find out more. I have trawled the internet for similar pieces but can’t find anything.

I wondering if anyone knows anything about these two pieces? The makers mark is under each picture. Many thanks in advance

There is no objective method of dating these pieces. You will have to make a judgment based on style. The handles on both pieces scream “art deco” so possibly 1920 - 1960 or so. Coopers remained in business until 1983 and Greenbergs until around 1945.


Yes, you can only make a guess regarding its year of manufacturer.
