An old Record 073 shoulder plane.
For general info about this tool, please see the FindMyTool.co.uk Record 073 plane review.
Condition: all parts working smoothly, the blade adjustment screw thread at the rear of the plane is slightly burred right at the top of the thread; the blade adjustment mechanism works fine it just means the adjustment nut can't be completely removed from the thread which there is no reason to remove, please see photos for condition.
