Well, I'm actually waiting on a FED 5V which is on its way from the Ukraine...I can't afford a Leica!!!
Anyhoo, one of the common 'problems' with these FSU cameras and their never-ready cases is that they smell like dead animals...One recommendation is to first clean the leather with saddlesoap and then to place the camera or the case in a ziplock with balled up newspaper. Change the newspaper once a day for a couple of weeks. Apparently this works.
