Origin and Year of Inherited Gold Ring

(Victoria, Australia)

A gold band ring (about 2mm wide) was handed down to me about ten years ago after my Grandmother passed away. We would like to know the year and origin to see if was hers or her mothers or possibly another relative. Its markings are T(?)M & Co (the o is high with a dot under it) crown 22 anchor (on its side) and one other separate marking which is very hard to decifer. It could be a lower case letter or ?symbol. Hoping you can give me some feedback or further information to source. Kind Regards Amanda
