Went to a tractor show today (Edgerton, WI) and saw a Ih corn sheller on display. Thought about about the one I put in the shed earlier in the year. A friend gave it to me. Started working on it this afternoon and realized I don't know anything about it. Missing the crank and I believe it's missing a piece of wood in the bottom. Stenciled on one side it sys "International Harvester, Chicago USA". All wood with 2 holes. Not sure what the second hole is for. Can see the old pinstriping, barely. Anyone one have a picture or maybe photocopies of a parts manual and any other info on it? Thanks!
