E's Front drive wheels are 8 bolt, same as K.
E's back wheels are 6 bolt, same as K.
E's hydraulic system pump/reservoir is same as early K [prior to sn 8201- I think?]. If not, the pump can be used elsewhere besides a combine?
E's engine is D17 tractor 226 4 cylinder, so if it runs good, you may want to offer it for sale at allischalmers.com tractor site. Even if it needs rebuilt, some of those guys may have interest. That engine has sleeve pistion design, so rebuild is better. A puller enthusiast may be interested as they will probably bore it out anyway.
E's clean grain elevator & return elevator may be same as K?
