My YTS-25 has the bell keys guard felts glued the the guards.
The YTS-32 has holes in the guards into which the felts are inserted. I assume this makes them 'adjustable'?
Looking at later '32 models and YTS-62s the holes have a screw in holder for the felts.
Is the screw-in type a cosmetic thing or has some purpose? If an improvement can they be fitted to the '32?

Thank you.

Assuming YTS 23 is the top one:

Then I’d say any advantage of adjustable is minimal.

It’s unlikely to be something you constantly need to adjust.

My 10m tenor doesn’t have that and it seems to be a great horn.
 
Bumper felt adjusters are really handy for repairers when it comes to setting up and balancing an action - but for the most part it's a one-time job. Set and forget...unless the horn/client has particular needs that require a tweak during play-testing.
 
You can adjust felt heights either with the screw variety (literally you use a screwdriver to turn the inserts ) or the variety where you 'screw' in the felts to the guard and you can to a degree adjust the felt heights by 'turning' the felt itself ...the latter of course exposing the felt to full view, thus having that certain aesthetic.
 
Once you get the felt height set on your 32, glue a little jewel (fake or otherwise) on top for that added bling thing.

The last overhaul I got on my SBA alto, the repair tech put some fake rubies on the bell key guard felt holders. Even on that road-weary horn, it adds a small touch of elegance. Like a once young and beautiful, but now aged woman living the end of her days in a small hotel that has gone slightly to seed. Still strong and proud.

This tech once put real diamonds on one of Sonny Rollins’ horns (at Sonny’s request). Sonny supplied the diamonds… He made the appropriate choice for me.
 
Felt or cork or "soft plastic"? Here is a adjust screw with a plastic bumper. Felt and cork are over the years going hard (compressed). This key guard to a Jupiter baritone, if I rembember right. Some "plumber tape" on the screw to prevent the screw to come loose.

MOP are nice but they are organic. I would go for brass or glas. I'm just now working on a Keilwerth "New King King". It has very edgy plastic "finger touches". If I have the energy I will replace the "pearls" with brass.
 
I don't really fancy doing a DIY job replacing the plastic touches, so I may ask my tech but not sure if it's worth the hassle and cost.
I was thinking of gently abrading the plastic ones with some sandpaper to give a rougher and grippier finish but I might just mess it up.
Not that important!

I'd forget about that entirely, for the agro involved, the difference between plastic and 'pearl' ones is imho infinitessimal to say the least, if you fancy some bling get a couple of fistf-ulls of Elvis style big costume jewellery rings to sparkle while you're playing ! 😀

If a plastic pearl/finger touch is not falling out, cracked ..... keep them. YTS 25 pearls are better than the pearls of a 1968 "New King". The pearls are bigger on a "New King compared to other saxes. The find real MOP to a sax with bigger finger touches is not easy. MOP on a sax is not so smart.
