Hello Chris, I can't remember all the invavlement of OLIVER and BEge just wonder how close they where. Mite have found a pan scraper with what I call a loading wheel that has a dolly wheel and tough pull with hydraulics. Just wondering how rare a guesstimat of value, its hard to beleive to find one here in so. Il. If it available to buy want to just preserve the history of items connected to Oliver and partners of the company.  Thank you for any insight   Boco
