Here's a nice package I saw on ebay (I have NO relationship to this camera or seller -- I just happened to see this browsing):
"This 5X7 pinhole camera in mint condition. It was only used once for an assignment. Included is 14 - 5X7 film holders in various condition, but all are light tight. Also included is a opened box of 5X7 Tri-X film with approx. 70 sheets of film in it and an unopened box (25 sts.)of 5X7 color duping film. The film has been stored in a freezer. All of the holders and film are not shown in the photo." http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1943330325 R.J.
