Featured Etched Shaker with Sterling Top

I have a pair of these cute shakers. Does anyone recognize the etch and maker? Not quite 4" tall to the top of the of the lid. The etch was hard to photograph but I think you can see it.
Thanks so much!

 

Its a Cambridge shaker, the pattern is distinctive.

 

Thanks, Tom. I tried going to a well-known etch site yesterday for an ID. After clicking on the site link, my computer was immediately shut down by Malware. I spent the next couple of hours getting rid of it, decided not to try the site again.

 

Thanks again for the Cambridge ID. I'm pretty sure the etch is Chantilly.

 

I'm not conversant with Cambridge's etchings or most of their patterns, and names for same are even farther off.
