It's quite nice to have a camera with a choice of shutter either a Focal Plane or leaf shutter, In my case I have a couple of Speed Graphics and an Ihagee
Zweiverschluss Duplex, of course these are large format (5x4 & 9x12).
My IIIa has had flash synch added, works fine. In the 70's I met a local Councillor (here in the UK) who's first job was camera repairs after WWII in fact he said most of his work was adding flash synch to cameras like Leica's. A good repair man should be able to do it today.
There's an intriguing flash synch for the 1931 Compur on my Ihagee Zweiverschluss Duplex, it's strange but works probably DIY.
I can't see why a pair of lens cells couldn't be mounted to a Compur shutter with a Leica srew mount, but where would the focus helical go . . . . .
