Best, Caterpillar and Holt Serial Number registry

Well its been somewhere around 13 years since i started this website (it was an expanded version from ACME list, which only covered D2, D4, D6, and had not been update for over five years) and with the generous additions (from you guys) that are added every year it has become a leading (if not the only complete) serial registry for antique Caterpillar lovers.

Over the next few days i will be adding the some odd 200+ tractors, once i have it updated if you would like to make an addition or correction please let me know.

If you have already submitted your addition to me, thank you for being patient, i have had some software problems and have just been able to get them corrected, nothing money could not fix...lol.

I hope that in the near future i will be able to add a registry for graders as well.
Anyway i hope you enjoy and thanks for your time!

Well i have it all updated as of today, if you have any additions please feel free to send them to me, email is the best way.

Thanks
