I'm a yard sale junkie. Here is a pic of one of my favorite finds. Sadly, I sold it recently but wish I'd kept it. I found it last year at a yard sale in Hollywood for the sum of one dollar -- no kidding -- mint condition and working to boot! It's a Baldamatic III. There were 3 or 4 lenses made for this camera. I have heard that this model will also accept Retina Reflex lenses but I never got around to trying that. Earlier Baldamatic models had fixed lenses and the "III" is rarely seen. The included lens was a 35mm Schneider. This camera has a spring wound motor drive mechanism for advancing film (the lever on the bottom is for re-winding). I love the look of these funky German chrome cameras from the 50s-60s though I find their controls to be a bit too finicky for me.
