Nonetheless, you should be able to tilt it back to easily change needles.

Trusting in your wisdom and experience, I looked at it again. I took it apart again and reassembled it.
It still appeared that the U-Tube had very limited movement. Yet, the arm appears to be identical to the one in your pic above.
After measuring things and actually calculating what the range of travel the channel for the set screw should allow, I could see no reason why it should not be possible to tilt the arm up and back. Yet, it wasn't possible.
So ... if at first you don't succeed, get a bigger hammer. I used undue force on the arm, pot-metal-damage-risk force, And what do you know? It is possible. It's just not easy. But it does get easier, if not easy, every time I move it.

I assume that the U-Tube
should move freely and that it should be a pivot point that allows the arm to deal with un-even records and records of different thicknesses, much as the one on my new-to-me HMV 102 does.
So I am thinking that I need to be a bit more aggressive on my attack on the end of the U-Tube. Either that or mix some light abrasive with grease and just keep working it back and forth, cleaning, testing, and repeating until it is free.
