I posted in the conversion forum about my newly bought tractors.
I was quite sure the Super Major was July 21st 1961 castingcodes saying J21F.
But in a different table, later Majors from 1963 can have the same castingcode but the date would be June 21st 1963
![Confused :?](./images/smilies/icon_confused.gif)
That date would be one of the last prodctiondays before the New Performance series started
![Shocked :shock:](./images/smilies/icon_eek.gif)
The engine was replaced, but the original engine number is suppossed to be 161250 4.
Can anyone bring some light into the darkness?
