Interesting, that's the same control shaft that's missing on my Philco 3118, those switches must have that as a weak point? I was debating on whether to replace it with another switch or a linear tapered pot, the pot would not be original but it would allow more variation then high or low. That set probably needs more work then your 60MB but since I found out that it's cabinet was different then the U.S 118B I would like to fix it up.
