Awww! You mean I had my custom 6x17 carrier made for nothing?
Some time ago I alerted the LF community the B+H was selling Omega D-5 126 carriers for ten dollars each. I bought a few (7)to qualify for free shipping. They have since been cut out to 6x6, 6x9, 4x5 and a couple 120 film 6x17 and this one that allows a 4x5 sheet to be positioned to the 6x17 cut out window. The locating pins are out of the way but hold the top and bottom together. I don't have a 6x17 back but wanted to explore that format with my Fujinon 75mm 5.6. I know the easel blades also work.
My friend Bob has a machine shop in his basement. Not a photo buff, but has rebuilt my Packard shutter and a friend's, cut threaded lens mounting rings and more stuff.Click image for larger version.
