I-10100 |
Pasco |
Shown in the 1910 Yale catalog page 850 made only in cast iron but with bronze or brass coatings. Easily confused with I-10110. The center of the Yale knob has a small bump inside a ring and a stem with a bump for a triplex spindle while I-10110 has a large bump in the center and different construction.
