I just found the website from which Zm table came from. Seem to have been updated with some new driver since. If someone need their theile small parameter :

just for giggles
year or so ago, friend asked if I can check one driver of his Kensington GR spks, problem was faint rubbing of bass driver VC, clearly present when SPL is low
what I did is usual thing - un-glue of spider, remove bolts fixing magnet to basket and inspecting everything
after that (no burrs, no foreign particles, just shoddy centering work), reassembly
pics in zip

Driver A ready for assembly again after hours of sanding and painting basket top and plastic ring. Looking OK, compared to what I originally bought:
Simply amazing job! 👍👍
Now, you are missing only that gold trim lines around. 😀
This might help. Self-adhesive 2 mm wide. Pure gold color, not reddish hue as in web shop picture.

I purchased one for an old tube radio restoration.

I don’t think these speakers ever had golden rings. Have considered it, but the gold is a bit OCD even for me 
Perhaps. Or maybe not? Maybe just for giggles, 🤣

They said the speakers used to belong to a theatre. But judging by the white residue, maybe it was actually a go-go bar?
In that case, they must have made mighty fine toe tapping music.

Yup. Getting more intel from Tannoy regarding substitutes. But what about calling Fyne?
got info from pinkfishmedia:
"Tannoy 33mm Tulip uses APGS15N
Tannoy 25mm Tulip uses APGS14"
so, we know at least first part of info is OK, so why not second part too
anyway, to have at least some reference, when you replace FF in gap , place tweeter assembly in place, then pull it out and put aside
take a picture of VC gap so we can see how much of FF is visible in gap
no need for chasing substitute - if you have some info regarding availability of APGS15N , share that
edit: just to confirm - you got tweet assembly through Lockwood? how much greenies it was ?
