Many thanks for reply. I saw itEach year we run a competition where people modify a Gold Dollar 66 and make it into a good beautiful shaver. You might want to look at some of those threads. This year one of our entrants posted this summary of what is needed. INFO! - 2020 Gold Dollar Mod Competition *EXTENDED UNTIL AUGUST* - https://www.badgerandblade.com/forum/threads/2020-gold-dollar-mod-competition-extended-until-august.587517/post-10701299
Other threads can be found in the compendium of the previous years’ competitions.
Hopefully one of our experienced razor modders will chime in. Good luck!
