Help with Gold Hallmarks

[beetle662]

Anyone that can help ID the gold hallmarks, please post. I found this ring at an old farm house (100 years old). What research I have been able to do shows that the anchor mark is associated with the Assay Office in Birmingham, England. I have sent them an email but have not yet gotten a response. The middle hallmark appears to be three stars, and the last one is either the letter M or W, depending on which way you hold the ring.

If anyone can help, it would be greatly appreciated!

Thanks in advance!
