I have been using a 'lens board' for the last year that is made from a piece of heavy (non-corrugated) cardboard, stacked with printer paper and glued together (So that I could make the bends in the layers to get the little tab thing) while I 'eventually' get around to making a proper one. The whole thing was eventually coloured black with a sharpie to make it look a little less like paper and cardboard glued together to hold the lens. (I basically just traced out the original board for each layer, left the pieces slightly large, then cut and fitted everything with an X-acto knife. It was messy, but I managed to do it without cutting myself.) Made small notches in the bottom for the two face screws, and cut a hole in the tab by just turning a knife point like a crude drill. I haven't had an issue with it so far, even if it is ugly as sin.
A few quick photos of my current setup, but I'll see if I can't dig up any photos from when I was gluing it up:

I suggest checking out your local Makerspace or similar group for a more durable lens board. It is on my list of 'things to get around to' for the summer, but I'll be sure to post up design files for whatever I come up with. I'm thinking a 2-3 piece assembly that is laser cut plywood that gets glued together, possibly with some register pins, is going to be the easiest/cheapest/fastest to build. I may try one as a 3D printed model, but as far as I can tell the original is 2 pieces of aluminum sheet, one of which was bent and drilled, and then sandwiched together, and 3D printing seems like overkill, and possibly not as durable.
On one hand I think it is kind of a shame that Pressman cameras get passed over so easily over fears of how difficult it is to find lens boards when they're so easy to fabricate, but on the other I'm happy that it seems to keep the popularity and price down. So maybe I shouldn't be sharing lens board solutions?
I have been happy with my Kodak 127 in the Graphic Supermatic shutter that I have for a general camera, but I haven't had any experience with other lenses on this one, so I'll be following the thread for more suggestions for myself.
