Are you talking mower conditioners like the 437 which became the improved 438 and the 129 which they did buy. I always though Shebyville made the first 2 and Owatonna made the 129. On that related topic where you helped the guy with his serial number and you mentioned no production, (77 Standards) are you sure on that because 53 &amp;amp; 54 production is all in the other style serial number range. I have seen 77 industrials that fit in that group. On the 1250 I think what you are refering to is the gas version which Oliver insisted on. We sold about a dozen of them for loader tractors. Once they got the carburetor fixed for American gas they were O. K. We were always told that some of that data came about because Cockshutt had the 411 over in Canada. That is the trouble with 40 year old imported stuff, With power steering they handle nice. The 500 gas had the same problem at least they had to rework those carburetors too.
