A GTL Smoothing plane with top mounted depth adjuster, somewhat reminiscent of the Norris adjuster (without lateral function). It is in unrestored condition. Very similar to the brass planes seen frequently on eBay, however this one is iron, and apparently significantly less common. The frog fixing screws are mismatched, but both fit fine and do the job they are intended for. Handles are free of cracks/repairs.
