I am the personal representative (nephew) of the Lawrence Duncan Estate and we are having an auction Sat. September 8, 2012 at 24284 Valley View Ln. Barnett, MO My uncle was an Allis Chalmers Collector and restorer we will be selling his working tractors and those in process of restoration at Auction, I had hoped to have serial numbers and model years but do not as of yet. There are tons of parts at this sale, some implements, we are selling a partially restored IB (fresh orange paint) and a G project that will need restoration, both have been garaged for years. Also selling a CA, D14 and a 5 yr restored strong WD45. He used the WD45 for work around his place grading roads etc. I apologize if this is an improper post, I figure this is information, if you want to attend you are invited.
