Most likely a Fulton Household line plane made by Peck, Stow, & Wilcox Co. (PEXTO) and marked by Sears, Roebuck & Co. in 1940-41. PEXTO operated from roughly 1870-1950. The #4 Household smoother sold for $.69 in 1940. I assume your plane has a stamped steel frog rather than cast iron frog. The Household planes were a lower cost plane than the rest of the Fulton line. The majority of Fulton bench planes were made by Sargent Plane Co. and Millers Falls Tool Co.
I have restored several of the stamped steel frog planes with good success. Not as pleasing to the eye, nor feel of heft, but they can be perfectly good user planes.
Here are some photos of a Fulton Household plane and a Fowler (stamped steel frog) plane restored to well above factory new. Both planes are capable of transparent shavings.
