Help with identifying an inherited piece

Hi there I’m new to the forum, I would really appreciate any information you could give on these pieces I have inherited, I think there American, does anyone recognise what the decorated M stands for under the word sterling Pleaseimage image image

I think you’re most likely right that the beaker is American, judging from the dearth of other marks. On a fairly quick search I was unable to find that maker, however. Does the dual salt cellar have the same mark? Or, are there other marks?

Thank you for your reply. Yes the salt pot does have exactly the same mark.
Kind regards

I don’t have that much expertise on American silver, but I think that mark must be known on one of the sites that lists American maker’s marks. I hope you can find out who it is!
