It would be interesting to have the first and last one built. Looks like #1 may have been destroyed. What about the last one?
I bought an engine from a dealer/rebuilder for the large John Deere tractor I have. The fellow that delivered it said the seller actually has the first and last 6030s built. Supposed to be a legendary tractor in John Deere's history but they just sell for what they can do as a tractor. One I tracked locally went to a rebuilder in Germany that buys them to fix up and sell as working units. He paid $6000.00 and expected to get $45,000 when completed.
Is the Krag with highest number of the last one built even known? Maybe the  were numbered receivers with higher numbers that did not get finished and were sold for parts?
