Tonka truck identification
Tonka truck identification uses wheel design, axle construction and cab shape; a replacement decal can carry an older-style logo on a later fitting.
Decal and construction
Look for TONKA branding on the cab or body and company wording beneath the chassis. Wheel design, axle construction and the shape of the cab distinguish models. A later replacement decal can carry a familiar older-style logo.
What to check next
Photograph both sides, the underside and the wheel hubs. Keep any model or product number with the decal wording. Compare the complete truck form rather than treating a printed copyright date as the manufacturing year.
