ALPS do make these, here is a link to the product page, the push-lock types they have are near the bottom of the page:

(Here’s a fairly cringe video of the core in action, with a lot of extra info about the board layouts, etc — https://www.youtube.com/watch?v=lbtxMdQE64A) I’ve got the core circuitry (48 separate synthesizers) and much of the downstream circuitry (resonators, etc) designed, built and tested, and I am currently trying to lay out the panel.

The original had these nifty retractable mini pots that can be pushed in flush the panel when not being used.  I cannot seem to find anything similar on the internet.  I was wondering if any of you had any inside track into where one might be able to procure such a thing.  I need a dozen of them, and I’d prefer if they were PCB mount, but that’s not strictly necessary.
