Vintage Chaplin's Improved corrugated number 4 sized plane.  Iron is a Siegley STS tapered blade but everything else is original and in very good condition for age.  Minor pits to body at rear on bottom and front on one side.  Rubber vulcanized rear handle is excellent.  Front wood handle has some finish loss but overall very good.  Levercap assembly has some loss to nickel finish but works as it should and blade depth adjuster works great.  All in all a nice example of an uncommon maker that unfortunately got steam rolled by The Stanley machine.  See photos
