Mochaware Slip Marble Agate Pottery Jug - Troyan?

I have this unmarked 4-3/4 inch tall jug. Clay is pale red. It has a high gloss mochaware type glaze. There is a name on shoulder applied after. It may be a place name so maybe item sold to tourist trade? I though maybe from a Torquay area potter but not even sure it is British. Possibly French?

European or Mexican tourist piece, imo. Signed, usually this is the name of the town where it was sold, but not necessarily where it was made - Grazzdos?
