In Figure 4. (inset) it looks like he's turned the entire soundbox on the tone arm away from the Pathé playing position to the Victor. Then in Fig. 5 he's pushed the stylus bar downwards to point the needle down.

He's some pics of my reproducer, imagine it upside down or that you are the record (be the record)...

The two slotted screws on either side of center in the reproducer are what I was refering to before (in a horribly cryptic way). As long as the pot metal isn't fudged you should be able to twist it.

Edited: for clarifications
Thank you for that. I see now what you mean. I think what I must do is disassemble it, as you have done, and treat it with 3-in-1 oil. It certainly does not move as it should according to your example and those in the diagrams.
Many thanks. Steve

However, if the pot metal has swollen, it may not rotate as it should, so dont force it or it might cause damage.
I've never done one of these, so others who have can probably guide you through getting it operational again, but generally speaking, anything made of pot metal that has a tight joint needs to be loosened with care and patience, and lots of penetrating oil. If the joint can be dismantled, it's usually best to separate the two pieces and very lightly sand any high spots that are causing the joint to bind.

I'm not sure if you've seen the operating instructions for the ultona, but here's a link just in case you haven't.

Yes, I think I'm yet another victim of aged pot metal. The diagram was most helpful so Thank You. Great. Another project machine LOL. I see some disassembly in my future. Many thanks. Steve.

Yes, there's no way it should be used like VICTROLAMAN shows in his video, unless you want to ruin your records. I imagine it would greatly increase stylus pressure on the outer groove wall, even though it's a ballpoint stylus, and is most likely the reason the sound quality is a little bit off (along with hard rubber gaskets).
A good rule of thumb with successful manufacturers like Brunswick is that if it doesn't seem right, it probably isn't :)

Mr Grumpy has the right idea with doing a full restoration on his ultona so everything operates & performs as it should. It'll make a world of difference to record wear & the sound quality once finished.
Good to see ;)

I'm sure you'll find it well worth the effort.
I believe the earlier ultona is more difficult to restore due to extra diaphragm & diamond stylus for Edison records, so yours should be fairly straight forward, especially since it doesn't appear to have any obvious signs of heavy deterioration.
Best of luck with it!
