Want to Buy WTB: Zeiss Box Tengor 54/2 or 56/2

Looking for a Box Tengor. Just needs to be 120 format. My goal is to convert it into a 6x9 pinhole camera, so lens condition isn't a worry. I would prefer one in decent cosmetic condition, however. It doesn't even need to a be a Zeiss, but I prefer the viewfinders and an ability to use a cable release.

Thanks,
