I don't have any information on numbers, but the serial number would start with 2R instead of R2. This should be a tandem drive chasis, weighing around 12,300 pounds with a 32 hp 4 cylinder gas engine. Went into production in 1939 and ended in 1942 from the information I have. This would have been produced concurrently with the Diesel 212 tandem drive of the 1R and 1U series and the gas single drive 8M series and the diesel single drive 1M
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."
