I have this little cased set of 3 KW film holders. They're metal bodied, with velvet light seals which seem to be in good shape. The film inside is likely NOT in good shape. Case lid has come off. Trade for Acros or Velvia in 35 or 120, or older discontinued emulsions. Expired is fine by me.
I'm in San Diego, CA so CONUS would probably make the most sense but PM me if you're worldwide and are interested.
