Rob;
Service information on many radios of the 1920s is very spotty compared to 1930s sets. Are these tuning condensers driven directly via a safe style knob, or is there some sort of gear reduction? If there is pot metal that could be responsible for a shaft being stuck, though you do mention a brass collar or bushing. The old mechanics trick I heard of was to use a mix of ATF and acetone, which apparently works better then just about an penetrating oil out there. Has it been removed from the chassis yet?
Regards
Arran
