Need More Help Identifying a Mark

I posted the other day regarding identifying a punch bowl set and had one reply. The picture on my posting was not very good and hard to read. I have found a mark on the punch bowl tray and one on the bottom of the punch bowl (don’t know why I didn’t see it before). I am attaching another picture and hopefully someone out there will be able to help me. I did go on the silver collector site but found it frustrating as there are so many makers and tried for awhile but gave up. I would like to know the maker and age if possible. Thanks!

Birmingham Silver Co of Yalesville, Connecticut. Company founded c1957, so the date is some time after then.
