Nice one - congratulations. I'm a Voigtländer SLR fan, but have just the Bessamatic.
The in-body leaf shutter is the bane of these cameras, since disassembly to access them is relatively complex. After about 10 years, I finally found someone (who wants to remain nameless) who is an expert on these and he fixed the jammed shutter on my Bessamatic perfectly and quickly.
The viewfinder display and operation of your Ultramatic makes me want one even more.
