Please Help ID old W.M. Mounts Gorham(?) silver

[Timestreasures]

I would be extremely grateful for help with identifying an old silver bowl I have.   At the very top there are two tiny designs, an anchor over what appears to be a crown(?).  (Is the anchor Gorham? or are these date code markings?) I don't know much about silver!!!

Any help with ID and approximate date would be truly appreciated.  I know the EPNS stands for electro-plated nickel silver.  I haven't been able to find history on the Mounts company.  Many thanks for any information or leads!!  Jane

Thank you so much!! I have been able to find information now about the company!!  I just was overwhelmed with so many marks to have to attempt to sort through with no guarantee even of finding what I needed!
