My darling wife bought me a present earlier this week. She found a Bessamatic Delux at St. VIncent Depaul for $25 with a 90mm lens! It needed some shutter help, but I managed to take it apart and get it working again.....after about a half hour trying to figure out how to re-assemble it! Anyway, I do have a few questions about it. First, there is a button on the shutter across from the flash sync selector....I have no idea what it is for. Also, there is a cover on the back of the top plate.....is it a cover to adjust the meter (zero? gain?) ? The meter is reactive, but I haven't checked it for accuracy. The only thing that bugs me is that the prism seems to be desilvered a bit. I'll need to fall in love with it before I get it resilvered!
