Identification Needed Please

Unsure what these tiny cups are made from, I believe they are AE Williams and sons silver plated, Circa?? Any help very much appreciated.

I think these may be pewter. The mark is definitely A E Williams of Birmingham but it is one which, as far as I can tell, they used on pewter not electroplate. 20th century is as close as I can get to a date - not much help…
