For your consideration, we are offering this Brown & Sharpe Precision Planer Shaper Angle Gage for Metal and Lathe Working. This is in nice usable condition. I believe it originally had a threaded knurled knob with it but have found examples with and without so may be an option. This measures about 5-1/6″ across the bottom and stands about 2-7/8″ up the left side. Be sure to check my other listings for more tools like this and other antiques and collectibles. Please see pictures for more details.
