Vintage Edwin Knowles 22 K Gold teacups and saucers marked 41-9

Vintage Edwin Knowles 22 K Gold tea cups and saucers marked 41-9 I have included some closeup pics of them as there is some wear on them as shown There seem to be no issues with the teacups One of the saucers the paint looks like it is cracking. I have also enclosed a 4th teacup and saucer. The issue with the extra set is that the plate has a visible crack on it so that is why I am just adding the 4th set. The cups measure approx 2" high 2.75" diameter The saucers measure approx 5.25" diameter
