Yes, Naphthali Hart, London 1812. It was normal for the London crowned leopard's head mark to be omitted on smaller items at this period. It was an anti-fraud measure to prevent the hallmark being transferred to a larger un-assayed piece which should have had the town mark on it. Other assay offices, notably Exeter, followed suit, but this is definitely a London hallmark and a London maker.
