Surpringly for me a couple of SLRs. First a post WWII Mentor 9x12 camera that needs the shutter overhauled as it's not functioning.
Second a very nice fully woring KW Praktina FX with a 50mm CZJ Tessar, it's the later versionwith a semi automatic apeture, it's a surprisingly well made East German camera - the first 35mm full sytem cameras and can take a bulk film back, as well as a motor drive unlike the slightly earlier Exactas. The build quality is excellent way above Exactas and Prakticas. The case shows the attention to detail, a button to activate the camera base plates rewind button, holes for the body's strap lugs. The film adanvance, mirror return and shutter are smoother than a screw thread Leica. I paid way below the typical market price.
Here's an odd TLR I found this weekend. The shutter works @ 100th of a second, but the speed dial and focus mechanism are frozen solid. Otherwise, is is pretty much pristine except for a bit of dust that can be easily cleaned.
