MIrror Adapter Lens

I recently bought an ASAHI Mirror Adapter. (90o lens)
It appears to be missing some kind of an adapter ring.
Would anyone know what I would need and where to buy an adapter to complete this lens?
If you look at 'Pentax 90o Mirror' above you can see the ring detached.
It is supposed to attach to the Tele-Takumer 1:6.3/300 but the Mirror Adapter is to large without the adapter ring.
Thanks

Looks like it uses step-up/down rings, however it looks like the version 2 has some grub screws to hold on the base adapter ring. If it's just a matter of step-up/down rings those are easily obtained. The base ring on version 1 appears to be 58mm and on the version 2 52mm.

Here is one (version 1 I think) in the Market Place archive

Amazing! The only place I have seen that sort of thing in the past was through Spiratone way back when.

Spiratone had two models - one was just basically a mirror box with a fake lens on the front. The second model was more like the 90 Mirror Adapter II with a round tube with fake lens on it. It was pretty obvious what the first model was.

Does it have male filter threads at all on camera side (where you would attach it to the lens)? If not the base ring is missing. I seriously doubt you can find one. You might be able to cobble one together using and old filter with the glass removed and a step-up-down ring.

Can you get a side view and 3/4 shot of the rear portion of the unit?

It does have the spinning ring and a set screw.
It looks like the adapter rings should do it.

Thanks for sharing the manual, very helpful.
It looks like I might be able to adapt it a bunch of lenses.....
