I need help. I have acquired an old push planter made by Sears. It is Model 980.1 per the tag on the handle. It is incomplete and rather rusty. It also has a 10x cast in the seed tub. It is interesting in that it uses a drum to dispense seed and not teh usual disc. I am guessing late 1800-1920s at the latest. Does anyone have an old Sears catalog from that time that may have a picture in it? I am going to try to get it going again and need to figure out the missing parts so I can make them. Thanks
