As Paul says, English, decent quality. Probably quite old, and worth a try at fettling it.
The cutter being Stanley isn't all that odd. A craftsman would replace a worn one with whatever he could lay hands on, and in a workshop it may even be that that were a number of cutters (sharpened by the lad) and you took one as you needed it. You often see Record planes for sale with Stanley irons, it causes huge confusion to some ebay sellers!
