<p>Thank you, David, for your candor. I definitely had some idea that they were unique and specialized (not seeing any comparable examples on eBay tipped me off) and I've made my living in commercial photography since the day I graduated high school in 2002 and became an apprentice, so I have some general knowledge of large format equipment.<br>
When I began as an apprentice we were shooting a Toyoview 4x5s system and we continued to do that until late 2004 when we switched to Phase P-Series backs on the Contax 645 platform. I loved the Phase/Contax system for its relative reliability and simplicity, but I feel very fortunate that I was able to learn how to do those now-forgotten large format things like loading 4x5 film holders, learning film sheet notches, setting up and zeroing that glorious Toyo 4x5 system, etc...I don't think most young photographers these days are learning those things, so I'm very happy that I got to do that!<br>
There is no hurry to sell these items -- they've been sitting cased for 5-10 years now in a closet, so the idea is to find out what exactly they are worth and attempt to get as close to that number as possible. As always, the market will dictate their true value.<br>
People like you are the reason that Photo.net is the place I come to for absolute information on things like these. Thanks for doing what you do!</p>
