Stanley planes by numbers 50
Stanley 50 Light Combination Plane
9 1/4" " long with 7 - 17 cutters.
Early models and WW 2 models were black japanned, later types nickel plated. Replaced the traditional wooden plough plane with a set of 7-9 plough cutters plus a tongue cutter, later upgraded to a beading plane with an extra 7 beading cutters. Later models were supplied with a chip breaker and a round screw to hold the small cutters without the sliding section.
Users seem to value the English models as much or more then the USA made planes. Same is true for the 71 router.
Problems: Chipped skate. Same goes for the 54. Plane and skate are cast in one piece. Check for chips under the handle and especially the mouth. The pointy bit is often chipped and rounded.
two parts often missing: round holding screw for small cutters and shaving deflector
