Tail seat tractors were not a standard production model, they were built that way using "attachment" options.
The one I'm looking at has a sp on end of serial number, it' a 1941 model. Was just hoping there were more records available. Thanks
Hard to get a true definition of "SP". Appears it may have started out as a catch all for attachments later to become just internal transmission and final drive parts. Still tail seat tractors never were assigned separate production numbers.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
