Yes, Fred, it does appear to be a Rushton. Many features match Rusthon- the stembands and the painter ring, ribs, the strip-built decks, the kingplanks, the floorboard shape, the buttons holding down the fllorboards, and even he blocks to which the buttons are attached- the little beading along their edges is characteristic of Rushton.
Measurements would allow a likely ID as to model. It looks like one of the very small models. It's in rough shape, but it could certainly be restored.
