K.R.Wilson Combination Machine value

[Don/WI]

I have the opportunity to purchase a K.R.Wilson Combination Machine complete with all of the babbitt pouring equipment, boring equipment, etc. I have checked it against the information in the "K.R.Wilson Service Station Equipment for Ford Dealers 1931 - 32 Catalog" (reproduction) and the "Parts List for Combination Machine" which has pictures of the parts on the back side of the parts list sheet. What would be a fair price to offer him for this equipment? I have no intention of using this equipment to restore engines. I just want to set up a display in a room adjacent to my shop. All comments are welcome except the ones that say "Are you crazy" because my wife has already told me that and she is a pretty good judge of character. I don't intend to show pictures of this equipment because those of you that know what I am talking about already know what it looks like. Thanks, Don/WI
