Lens recommendation

[Donald Miller]

I have located a replacement camera for the one that was stolen recently. It is a 5X7 Wisner technical field and I want to outfit it with a single older lens. What I don't know is what lens will fit on a 5 1/4 Wisner lens board. I would like something in the 12 inch focal length in either a Petzval or Heliar. I would appreciate any input offered.

No one?

Donald,

the flange OD on my Heliar barrel mount is 120mm / 4.75"
the flange OD on my f/5 B&L petzval is 108mm / 4.25"
both should fit.

Good luck with it.

Donald, i just measured the OD on a 14" f5 Wollensak Portrait lens and that is 5.25".
A 12" Heliar if in a shutter would most likely be a #5 Compound and the flange on that shutter measures just over 4.5"
So, you should have no problems with a 12" Petzval or Heliar.

Thanks Jan, I appreciate your time spent in checking on this.
