I have one holder if this is what your looking for, I was kind of holding on to it as a reminder of my youth, but if you have a use for it, I would consider selling it, what would you offer? It does however need the dark slide replaced, the pull tab end is missing. I buy and sell anlog photo gear, was doing it on ebay till I got screw over after 14 years of 100 % positive, so having to change my selling options, but here is my site, I buy up old darkrooms and film cameras and sell them... I have a lot of basic stuff, but other than an extra Bessler 4x5 I am short on that gear. I use a Cambo mono rail.
