Looks good Mark. That rail at 2.875 is 50% I think so that's good (from memory 3 is 0% and 2.750 is 100%). Pity it wasn't over 13237 because that's when the two-piece clutch shaft came in but on the other hand, it has the short rails so more ubiquitous. Looking forward to seeing either of them run! : )

Ok found the Goughs serial # listing:
- 5J3036 - R. Raine, Stoke
- 5U519 - F.S. Nola and Sons, Ltd. - Auckland (Kumeu)
- 5U5576 - B. Linnell, Kaiwaka
- 5U6373 - J.R. Byers, Gore
- 5U13058 - I.K. Campbell, Heriot
- 5U15604 - C.A.E. Cashmore and Sons, Ltd., Auckland
- 5U18507 - W.R. McNabb, Nelson

The one from Auckland migrated a fair distance. Let me know the serial # of your cousin's Twenty-Two and I'll look it up. I counted up the # of units that were listed specifically in Marlborough and it's a pretty decent # - 5 Two Tons, 26 Tens, 18 Fifteens, 12 2F Twenty-Twos, 14 1J Twenty-Twos, 3 4J R2s, 6 6J R2s, 5 3J D2s, 21 5J D2s, 64 5U D2s, and so it goes. At the time these listings were printed out, there were 406 Twenty-Twos imported, and 1838 D2s/R2s. Seems like a lot for a fairly small place where the import price was high.
I got this listing from John Neal who hails (hailed?) from Budge St, Blenheim I think about 20 years ago__PRESENT

If you collect any serial #s, send them to me and I'll look up who Goughs sold them to. This listing goes up through 5Us, 7Us, 9Us, and 2Us for example, so '50s-ish. It doesn't have any of the tractors that also came out in the 50s such as 14As or 36As, D9s etc.
