For sale are 6 nice wheels, they measure 5-3/4" in diameter with a roughly 1-1/4" tread. They have a 1-7/16" bore, threads for a grease fitting and an internal pocket for grease. They are marked MM  and CR 476. 2 of them have a partial shaft driven into them, looks like it would come out after soaking in some oil and some applied pressure. I would prefer local pickup but could ship if need be, I can add the cost of shipping at that time.  I am located in Sterling, IL
