Looking For An Adapter

[dynachrome]

I am waiting for the delivery of a 100mm f/4 SMC Pentax bellows macro lens. It will be in good company with some similar bellows macro lenses in my collection. I don't remember whether I have a Pentax K mount bellows. I want an adapter with a female Pentax front and a male T mount rear. This is usually called a T flange or a reverse T adapter. It will allow me to use the lens on my Vivitar, Soligor and Spiratone T mount bellows units. So far I haven't been able to find one of these adapters on the usual websites. If Spiratone were still around, they would have one. Any suggestions?

You just have to search the auction sites on a daily basis. They do show up every once in a while. I remember selling the Vivitar units when they came out in the 70's, a very neat idea for macro work. I'm still looking for an Olympus OM lens flange. Like an idiot, I did not buy 1 each of all the mounts when I had the chance.

I don't remember how many of these different adapters I have but I'm pretty sure K mount isn't one of them. A second choice would be a glassless adapter with a Pentax K front end and a Nikon F rear end. When I got my first 100mm f/4 Yashica ML bellows macro, I got a Y/C to Nikon glassless adapter. I have a Contax bellows now but I like being able to mix and match and use different lenses with my Canon F-1 cameras.
