I doubt theres any 90/110mm lenses with a 140mm flange distance for infinity focus.

Sounds like you'll need a 150mm lens to make infinity with your setup.

That is what I am fearing for a 90mm.
There is a very expensive SK 110 lens on Robert Whites site at c£1700 which would foot the bill as the rear lens group looks to be c 25mm in overall length - if I can find a used one for £450 and fend off the competition with a stick I might be in with a chance - but Ive not even seen a used one under £1000

- Nice website Dave by the way.

You might try a plain 90mm angulon,as they are so compact the back of the lens doesn't stick out of the shutter at all. Still only a 90mm flange distance though, so your standards will get pretty close, maybe a recessed board would work?

Thanks for the website comment, i do my best!
