Help to identify this Gorham pattern

[larrywseale]

Hello:

I need help in identifying this Gorham pattern. It is very similar to the 1926 "Old Colony" and the marks appear to date it in the 20th century but it's not quite right when I compare it to an "Old Colony" master butter picture & I can't find a closer pattern. It's 6 9/16" long. Help appreciated as always.

I'd say it's the 1875 Mothers pattern but that will need to be confirmed because there are other patterns that are similar.

Thank you. That appears to be it, right down to the raised vee on the underside.
