My 1956 Smith Corona Skyriter with vestigal return lever…
First remove the carriage cover of the 6Y machine – you need to do it to access the one screw that holds the carriage return assembly in the machine.
Yep, that long screw at the top of the assembly is all you need to unscrew once you have all the cruft off. This screw is directly accessible on your older metal-body Skyriter.
Sadly, the vestigal arm doesn’t clear the added plastic bodywork on Cougar 6Y. Guess you’re a parts machine now, you poor victim of 1960’s excessive bodywork bloat.
Weapon of Choice, with phat new chrome shifter. Vroom, vroom!
