I picked up an "untested" Yashica 124G on eBay for $45 while trolling "newly listed". I could tell from the pictures that it was going to need some TLC, but figured it was worth the money just for the experience of getting into the guts in case one of my (much nicer) Yashica TLRs had an issue in the future.
When I got the camera, the shutter would fire, but the blades wouldn't move, but you could tell they were trying to open and close. Removal of the rear taking lens element and a quick poke at the blades fixed that issue, but the shutter speeds were off and anything below 1/8th wouldn't complete without coaxing. I took the shutter apart, but left it on the lens board and used my trusty Tri-Flow to get everything back into shape. Speeds seem accurate (I still don't have a shutter tester), but the self timer is still non-functional, though not really a concern for me.
The meter was also non-functional and took some poking at to figure out it was shorting on the body. I know the meter is supposed to go on/off with the opening/closing of the WLF, but I couldn't figure out how they were supposed to be mechanically connected, so I moved the contacts to an always-on state. Not my favorite option, but for a $44 camera, I wasn't going to make it like new and now the meter works (and seems to be fairly accurate.)
This one will probably go back on the bay for a little profit and much-required experience was gained. I just need to glue the leather back on the front and focus knob side.
