[redlineoryourmine]

i have finally found a guy that has a book that tells which is which with the MG-1 i wont use his name because i did not ask him if i could but here is what he told me is that the john deere ones have a different serial number which is like 1DA000 and up they were built at a different plant i dont remember which one he told me. ill chat with him again soon and the others that were cletrac  built are like the 1JA000..they were built at the other plant he told me but dont remember which lost the paper. so it looks like i have 3 john deere and 2 cletrac built ones here in my yard. the best 3 i have are john deere. if this is incorrect let me know im sure he knows whats what when the guy has 20 some cletrac not all military. this is what is great about lists like this is the way to spread info to the world thanks for the help guys and thanks blake hope to get you some pictures soon of my cletrac im going to build.i need to pull it out of the line up first. still looking on what kind of pull type road grader they used ?

1DA000-4DA948 were built by Deere @ Moline; 1JA000-15JA488 were built at the Cletrac plant. The rear ens were B Cletrac's, and the transmission's were Deere's built by the Iowa Transmission Co. a Deere owned War time Co.  I think the transmissions were built in Waterloo where they also built tank transmissions.  Spark
