I haven't looked into any of the production numbers of tractors that were built at the MM factory in Hopkins, Minnesota, which would include the 2655. I hate to run you in a circle, but try asking on the Minneapolis Moline forum at Yesterday's tractors. Looking at some of the recent posts there, it looks like some of them might know.

Here's a link:

I've got to think it would be a low number, should be interesting to see if they know.
