Philco did similar on some of their 50's split-chassis sets...Only the permanent magnet was enclosed in a fixed mounting bracket which contained a screw mechanism to move the magnet that had a flexible adjuster shaft that stuck out the back...You're right GE was comparatively cheezy on their system.
