Hi All,
I have three marks I’ve been trying to identify. Can you help please?
This is on a glass powder box with sterling lid.
This is on a glass flask with sterling.
This is on a modernist sterling bracelet.

Your first mark is (most probably) an American sterling mark. I’m not sure what the letter combination might be.
The second is a London sterling hallmark with the date letter “l” for 1906/07.
I have no idea about the third mark.
Your second mark has the makers initials which are just out of shot to the left 
Thanks to you both! Adding the makers initials from the second photo. Sadly hard to read but thought I’d give it a try and see what you think.
The maker’s mark is that of Drew & Sons. The initials on the mark are ED over JSD for Ernest & John Summers Drew:
However that causes me a small problem as this mark was not registered until 1914 so my reading of the date letter must be wrong; I suspect that it might be a slightly deformed or damaged “t” for 1914.
