I've a whole bunch of odd lens boards most I can identify but not these two aluminium boards. I remember one came with a Paragon lens no idea about the other.
The first is on the right in both photos is 10.1cm (4") square, it has a thin raised bit about 2mm in on the back. and a casting number 105822.
The second is 8.8cm (3.5") square, I'm wondering if it's a lens board as it's threaded to take an M39 screw fit lens. The back is raised 1/4 of and inch from the edge.

The first s likely for a Calumet.
The second appears to be for an enlarger.
Thanks. What sort of Calumet as there's quite a few different Calumet cameras and it's nothing like the o Cambo (Calumet on the US_ cameras I've seen or owned here in the UK.Originally Posted by Jim Noel
I've never seen an enlarger with a square lens board but I guess they must exist.

If I remember correctly from my newspaper days as a photojournalist back in the late '60s, our Beseler enlargers used square lens boards. And, yes, they had 39mm threads.
The Calumet board is for a CC40x series, which was based on the 4x5 Kodak Master View.
