Looks like you got the bug! Good luck with your search! They are out there and while rare, much more common than say the elusive 500mm PQS tele-APO-tessar. I think they come up on ebay every few months.
btw - Dr. WA has one - optically the same as mine as I made side by side comparisons, but not in mint condition appearance wise - not sure if he'll sell but you never know!
