Wardner,
As I commented on the classic truck board, in your quest for big IHC based wheel tractors, you ought to look for a MRS-14 or a MRS-18 to add to your collection. They would be a very rare find, if any of them still exist. The 14 used the UD-14 engine and the 18 used the UD-18 engine. MRS started building four wheel drive tractors in the late 50's and stopped producing the two wheel drive IHC powered tractors at that time. At one time, during the 60's, MRS produced a tractor/scraper for the strip mining industry that was, at that time, the largest production tractor built in the world.
