hi

I am curious as to know the date of the cameo I have

it has the makers mark ejcy&co

it also has
8/30
I am presuming there were 30 made
also the lters jt also assuming that's the assistant etc

the hallmarks are
sideways anchor 9.375 and the letter "s" I have narrowed the s to 3 dates but unsure wether its early 18th century early 19th century or late 20th century as the letter s is very similar in all three please help
