Enamel bowl, signed. Any guesses on sig?

Enamel on copper bowl. The center section is a bit unique.

Any leads on signature? I suppose could be a homemade piece, but were people doing enamel on copper as a home craft?

Someone pulled back the GW tag (not me, I would have done it more neatly...) Just doing some research. Thanks.

 

Don’t know if this is right person but the sig looks like V Rolfe to me.

 

Thank you, Houseful.

 

Yeppers. That dish isn't novice work.
