The reason you see more Wayne 60 pumps restored than #34 Tokheims is they produced more 60 pumps.
The #34 was only made for 4 years 1934-37, Wayne 60 was produced for 11 years starting in 1935 when the 12" computer was introduced into service. The 8" computer only had about a 6 yr production period.1932-37?
The 60 took a 12" computer, the 34 took an 8" computer.
By 1937 MOST pumps that took an 8" were phased out, possibly due to the fact that VEEDER ROOT may have not had planned to continue making the 8" and 10 3/4".
So with the 12" computer, form(of the cabinet) followed function.
By 1935 most NEW CABINET Designs did not have a smaller top housing for the smaller computer, and to continue using a smaller computer would have made it more inset into the cabinet making it harder to see from the side while filling a car.
The 12" computer became and is still the standard size today. It may well have been the actions of VEEDER ROOT that killed the pumps that used the 8" computer.
