.965 compression ring adapter for 1.25" focuser

Would anyone know where I could aquire one of these. The only one I can find online is for a specific Takahashi telescope. Theres no pictures of it so I can't exactly tell if it screws in or works with a standard diagonal. I assume it screws in.
Any help would be appreciated.
Thanks Fred

I believe that adapter is specific to Tak diagonals to convert them. I have seen a few compression ring ones from other sources but don't know of any commercial ones carried here (USA). I bet the Japanese manufacturers make them as .965 stuff is still popular over in Japan - but probably not imported regularly.

To solve this I bought a Tak compression diag and just replace my original 1960's one - It only costs like 60 bucks new - used here on Amart can be much less - and it has typical Tak construction and performance. Of course you can also just put an ad in and see if someone has the adapter your looking for.
