This is an E. C. Simmons Keen Kutter K240 scrub plane.  It is embossed in front of the knob K240.  The blade has the Keen Kutter logo and wording E. C. Simmons Keen Kutter and cutting edge is 1 1/4".  The bottom is 9 3/4 inches. The knob and tote show normal wear from usage.  I would call it very good condition.
