For additions or correction please contact chapter12@acmoc.org
I would like to thank Tom Madden for all of his help in putting this page together.

Heidrick Ag Museum Best Model 30 "Humpback" only one know to survive
1913 uk Heidrick Museum Woodland CA. humpback, orchard
Please note:
Serial Numbers or "Tractor Numbers" for Best Model Tractors have the following "Letter" at the beginning or end of the serial number.
"A" Best Model 60 SN location listed below
"B" Best Model 25 SN painted on track roller frame
"C" Best Model 75 SN painted on side main frame
"D" Best Model 40 SN painted on track roller frame
"S" Best Model 30 SN location listed below
If the number on the tractor does not include the right "letter" for the model of tractor then it is the Royality number.
The Royality number was issued after Holt and Best settled their litigation around the begining of 1919.
The serial number and royality number may or maynot have the same number of digits,
in most cases the serial number will be a lower number than the royality number.
The royality number is located on the brass tag with the pat. numbers listed, the tag is sometimes mounted on the fenders.
The serial number is located on a tag that reads "Tractor Number", which is located in the following locations:
On the left side on the engine block
Directly under the water pump-for the model thirty
Below Cylinder #1-for model sixty
Left side of seat base, or just above the draw bar on the transmission housing.
The List below has been generated from information I have recieved from machinery owners and from different publications.
see source page.
