Records on this model are incomplete. Advertisements of the era show "Sure Grip, Never Slip" written on the cooling tower, and some have assumed this to the model name. The model P designation is suggested in the January/February 1995 issue of Two-Cylinder Magazine. The tractor would appear to have been based on the unsuccessful Parkhurst-designed Waterloo Boy Standard tractor.
