5/16 ths Side Bead moulding plane by Shepley who traded, at least from 1771 and probably before until 1805 in London.
So its at least 220 years old and quite possibly 250 years old. There is an old crack in the wedge but it seems solid.
Makers mark is nice and clear.
Plenty of length left on the iron- which is clean but will need to be sharpened, if it is to be used.Just under 9 1/2 inches long.
Overall a nice early boxed plane.
