History & Design
History
Made from 1898 to 1943. The flat-sided types after 1911 let you adjust the frog without pulling the iron, using setscrews at the rear of the frog.
Design
The same 9-inch by 2-inch footprint as the Bailey No. 4, but with the full-width Bedrock frog seat for a more solid bed under the iron.
For Collectors
The easiest Bedrock smoother to find, though still priced above the Bailey No. 4. A clean flat-sided example is the usual goal.
