1206WMO, It is almost impossible to tell exactly how many gas 99(6) Super 99 gas and 1958 production of 950 gas tractors were built. All three of the above listed tractors were built in South Bend, Indiana plant #2. There are records to indicate that there were a little less than 600 gas engines shipped to that plant from late 1952 to late 1958, when production stopped at that plant. In that time frame they built the farm 99(6) as well as the farm and industrial S99/ and the first year of the 950 tractors. Also the stationary power units were built there. There is no way to tell how many engines were shipped in any one year, just the total over a 6 year period. It would be easy to say that 100 engines per year times 6 years would equal 600, but it's not quite that simple. The 199 and Super 199 skid mounted power units were being built in the same 6 year time frame, and when they were mounted that way I know some of them were converted to natural gas and used in oil field work. With the above information it is only a guess on my part, but I would say there were approx. 60 gas 99(6) tractors and 15 gas power units built in late '52, '53, and early '54. In late '54, '55, '56, '57. and '58, when the supers were in production, I would guess there were approx. 325 gas tractors and 150 gas power units built. I would guess the '58 production of the 950 gas tractors would have been approx. 50 tractors. The '58 power units were built only as the Super 199, there were no 950 power units. I WANT TO CAUTION YOU, AND EVERYONE ELSE READING THIS, THAT THIS IS MY OPINION ONLY, BASED ON INFORMATION I HAVE GATHERED. NO ONE ELSE CAN BE BLAMED FOR MY OPINION EXPRESSED ABOVE.
