Vintage Stanley Bailey No. 7 Smooth Jack Plane.
Bed of plane is a type 11 with 3 pat dates, approx 1910-1918.
The frog looks to be the original to the base.
The Lever cap I believe is a type 12 from 1919-1924.
Unsure if the iron is the original. The chip breaker has definitely been replaced.
Everything moves freely and the iron is sharp.
