My original post was about the materials use for the S-38B tuning extension shafts. Having now pulled the chassis out of the radio, it turns out that the shafts, which were made of plastic, had been snapped off just inside the case. What made me think they were extension shafts were some spacers that had been added between the metal case and the tuning shaft support brackets. I will make up two new shafts from plastic.

Sorry to give mis-information at the start of the post, but the ensuing conversation has been most enlightening.
