Pack 44 follows the same rules adopted by the Daniel Beard Council with one addition.

Your wood block has been stamped with two logos on the bottom, near each axel. At least a portion of one logo must be visible (painted or unpainted) when the car is presented for inspection.

(Basically, no one is permitted to use a car purchased on eBay, Etsy, Amazon, etc. or a kit sourced from anywhere other than Pack 44. You must use a kit provided by the Pack. You can purchase different color wheels from the Scout Store, only official BSA wheels will be permitted.)
