The original Series Three is a new tool.
There was a parts change circa 1954 with no change in box nor kit number. The 32" black tires were change to 34" kit colored wheels (yellow) with the rear tires now having brakes; the roof now had tibs inside. Thete should be a duplicate box on the timeline noted "changed parts." I will try to add it again.

Moreover, the product timelinr should show the Franklin release as "changed parts" also.
