What Are These 3X3" Lens Boards for?

[jimgalli]

They are metal with rounded corners exactly 3X3". The light trap inset is 2 7/16". They have a threaded bracket area that looks like they were held in place by an outer screw. One is copal 1 and one is copal 0. Will offer for sale when I can describe them intelligently. Thanks for your help.

Given the setup process and time needed to deal with that screw, I'm guessing they're for a process camera of some kind -- or an enlarger.

My guess is medium format view like a Plaubel or some such but hard to offer them with guesses ;~'))

Jim, you might reach out to SK Grimes and see if they have any ideas.

I once has a horseman VHR, the lens boards you are showing are similar to the VHR. I think !!! That was 20 years ago

I’m wrong/ disregard my previous post.

That was where I went first. yes, they were 80mm X 80mm

I've never had one, but my guess is one of the press cameras with unusual boards, and specifically some type of Busch Pressman. I don't know what size though, model C, D, etc.

Hi- that is for sure a Busch Pressman lensboard- I had the 4x5 and the boards are very small and that tab on the back makes it hard to DIY them. Hence, I no longer have the Busch

Those Busch Pressman boards are very hard to find. Someone will want them.

Yes, they are not easy to DIY but I have done it.
