I wanted to try one last time on these forums, to hopefully find someone in the US that might have one lying around.
In response to my ad, today I received a note from another senior member on these forums that might have one for sale. If that option does not work out, I will reach out to the the person you've recommended. I have looked at his work in the past - clearly he knows what he is doing, and has done a great job in restoring/fixing these old backs.
Thanks for all the links and info.
