I have a red, Selle Italia SLR, very sexy looking saddle, only used once for approximately 60miles. I would be happy for you to try it out, it has a cut out in the middle.
I won't be using it again and will be selling it at some time.
Will look for a pic on the web

Sorry to hear about your woes, I know how you feel.
Anyway, I previously had numbness in a certain delilcate area but this has disappeared, even with the Brooks which doesn't have a cut out I don't get any numbness, so for me the answer wasn't just about having a hole in the middle.
What sort of position are you riding in for the majority of the time?
Have you lost all sensation? Sorry for such a personal question but it is necessary to know all the facts in order to give any proper advice.
Photographs will not be necessary
