Well, I might as well jump in with what I have. That includes, I believe a Weston II and and Weston IV. My mom kept the little instruction booklet for the latter model. After she died and I went through her possessions, I came across a very nice, handwritten letter from the Weston Corporation, answering a question of hers about the meter. I also have her old Luna Pro and and a new model I purchased, as well as a Pentax spot meter. -- http://www.davewyman.com http://www.icyclist.blogspot.com (cycling through the meaning of life with bikes, cameras and computers) http://www.pbase.com/davewyman (my photography galleries) This mail is a natural product.
