In my case I startged out with a pre annaversary Speed Graphic (4x5 ) and made my own lens boards from plywood.

Then I got an 8x10 Kodak 2D and put my one lens that would cover on a shop made board.

Later on I got a Wista 45DX with those cuter little Toyo-Linhof notched boards. Got three lenses for that rig (90-150-210) on compatible boards.

These now can be mounted on the 2D using an adapter board on the Kodak (the 90 won't cover at infinity of course).

However, there is a long-plan to set up a Packard shutter and vintage brass lens on a dedicated wooden board for the Kodak.
