I have a 1937 GMC Model T14B. The wheels are 6 lug.

1) Does the "B" in the model number indicates that it is a 126" wheel base? Or, does the "B" indicate something else?

2) The chassis number is metal stamped into the data plate (positioned center on opposite firewall side; inside cab) and also stamped on frame on passenger side slightly forward of the RF wheel.

3) The chassis number is: 21333

4) The engine number (stamped on the horizontal surface of the metal pad, front left of the head) is: F616294

Any assistance with this would be appreciated.

Thank you.
