I have talked to two design team members for the 2255.  One says I probably have a prototype that was not assembled on the line.  So it would not have a build card.  The other says it was policy for those tractors not to leave Charles City with that serial tag.  However,  other tractors have made it out of the factory.  For example, the prototype AT4 Moline has been located near Charles City according to one gentleman I talked with.  So I guess it is possible.  I'd like to talk to Duane Starr about the picture on the back of the last magazine.  This photo was taken about 43 days prior to production beginning.  I wonder if this is my tractor???  Both design crew members will be at Dover, it will be interesting to get them together and see what they can come up with.
