<p>John-Thanks, I'll check this out.</p>

<p>Well, I Googled "reverse T adapter" and "reverse T-Mount adapter", and with one exception, all the hits were adapters for reverse mounting a lens to a camera using the lens' filter threads. The exception was a 'REVERSE BAYONET T MOUNT ADAPTER for KONICA SLR". I changed the "KONICA" to "Pentax PK" and tried the resulting description as a Google search. No luck. I have found several forums in which such adapters are discussed, and perhaps as I explore these, I'll find a source. The Zykkor bellows for the PK may may be the best alternative. Since I already have several bellows, I'd like to avoid adding another to the collection. Thanks, Jeff.</p>

<p>Thanks, I've found the bellows you refer to. </p>

<p>Thanks for your prompt response. I've searched eBay for "inverse T-mount" and "T flange (as described in an old Spiratone ad)" and so far have found nothing. I'll keep looking. I've also Googled both terms without success.</p>

<p>I want to mount this lens on a bellows which has a female T-mount adapter for the lens. Is there an appropriate adapter--K bayonet to accept lens and male T-mount threads to fit bellows?<br> Thanks,<br> CWT</p>
