identifying galleon or ship like mark - any ideas?

[size=18]I have a small silver box, patterned on top. hinged top. plain feet. Ribbed underside with a sailing ship with 3 sails - maybe a galleon? I guess it must be silverplate since there aren’t the usual marks. It is heavy.

Thanks in advance for any advice.

Sorry, no idea on this.
