Model T Jumbo Giant aftermarket 3 speed transmission

[Jim Rohn]

I am not sure how many of you knew Wally Heater, but his widow held an Estate Sale this weekend. I found this on one of his his benches:

any info on this make avail? It has a patent date of 1915 cast into it

My mom and dad used to tour with them all the time in the Michigan area and apparently Wally's Model T was quite the highway cruiser

All the cars are gone except his 66 mustang Coupe, they want $10k for it ...
