Topcon Uni and Auto 100 has leaf shutter and its main selling point at that time was that you can use the flash all the way up to 1/500 seconds. It had different interchangeable lenses.
You can buy this camera cheap now but most of them are broken. the weak point was the shutter cocking cam post. It break off and shutter no longer winds. Also, the prism goes black from the deteriorated sponge used in the prism. I have made a downloadable pdf instruction manual on how to do aperture cleaning on this lens.
