Tal 2 Eye piece confusion.

[Si Ricketts]

Evening all, to set the scene, I'm a newbie to telescope ownership and came home with a very tatty Tal 2 yesterday. It’s been in its box for years. All sorts of issues I knew about before buying, non working motor drive, bad cosmetics, possibly some bits missing. Good bits I 'believe' I new about, good primary and secondary mirror and all the relevant standard extras, eye pieces, filters, screwdriver etc etc. 

I bolted it together this afternoon and observed the moon,  Jupiter, with one ring (which I could not believe) and 3 moons and I even got a glimpse of a pink fuzz of Saturn near the horizon. All a first for me. All done with the Kellner f15 eyepiece.
 

My first of many questions, I'm not quite sure how to use the eyepieces. The f42, or any other combination of the eye pieces, with the exception of the Kellner,  would not focus. 
Looking at the manual, see attached pics, it looks like there’s a piece missing which fits between the eyepieces and the focusing mount. Also if I carefully held the f42 eyepiece away from the focuserI could get a clear image. Hope that makes sense. The extension tube with the silver locking screw looks like it should fit on but the eyepieces are to small to insert into it. I wonder whether this is an incorrect replacement for the original Tal extension tube?  
I know there are issues with some Tals as they have 32mm dia eye pieces, I've measured mine at 1.25”.  
Any ideas..?

Looks like the OTA has been designed with AP in mind, as the focus point is well outside of the eyepiece, to allow a camera to focus.

So you need either the screw-on extension, that is likely to be impossible to source.

Or a long 1.25" extension, something like this, they stock various lengths:

I hang my head in shame. After a bit of experimentation this afternoon I got the eye pieces working with a bit of sawn off water waste pipe. Whilst celebrating this little triumph I was looking at the 15mm eye piece, the only one that worked,  which I though had a fixed screw mount.  Yes, you guessed it, it was pushed in and the little clamp tang slot was full of fluff and rubbish so looked part of the tube 🤦🏼 If you have any forum awards I’d like to put myself forward for newb dumb question of 2022.  Thanks Micheal for taking the time to come back to me. Onwards and upwards.
