1920s Brunswick 110 needle thumb screw repair

[ZGMB15]

Hi, I'm new here and to this whole phonograph scene, so please bare with me if I seem misinformed.

I recently got a 1920s Brunswick Model 110 (with what I think is an Ultona reproducer) for free, and it has a whole plethora of problems. What I am most concerned about, and why I'm here, is that I need help in deciding what to do with the needle thumb screw. It has broken off, so there is no head or much of it left that is above the threads of the reproducer. I am already mechanically inclined, since I collect and repair typewriters, but this is way out of my area of expertise. I can get a replacement tone arm and reproducer off of ebay pretty easily, however I would prefer not to since I already have to shell out cash for another crank and I just don't want to spend anymore money on it.

My question is, what should I do? The tone arm and reproducer is already not in the best of shape, so is it even worth repairing? If so, then how would I go about doing it?

Any suggestions and comments are greatly appreciated, and any advice goes a long way as well. Thanks

Well, I would definitely not change an entire arm and soundbox only because the thumb screw is broken. It's a small part and compatible spares are readily available.

Concerning the overall conditions of the tonearm and soundbox, without a picture it's impossible to judge and give advice I'm afraid.

I have a box of Ultona parts and can almost certainly supply the thumbscrew you need. I'd suggest you post pictures of your tonearm and reproducer, then send me a PM so I can let you know what I have.
