No, not the taught psychological cinema thriller, but my own taught psychological thrills while trying to figure out why my vintage shutter only worked in one speed ("T") Turns out I had accidentally let loose a small brass cylinder in the works which needed to be reattached, and I had to bend up a small worn nub of metal to engage some other speed-thingamabob. It's all very complex, but now I can honestly say that I have stared into the face of a shutter mechanism and lived to tell the tale.
I took this to document where are the parts were before I started messing around, but as an appreciator of fine mechanical handiwork, I realize now how pretty this is, too, in its own German-functional way. Hope you appreciate it, too.
