I found another link that said the K-22 was designed for, but never used for, recon photography. 9×9″ negatives on the k-22, said it. No e-bay history, though (closest was for a 24″ cone, and it only went for $30).
Oh well, the pair only set me back $20. I’ll find a use for them. They are lovely little boxes.
Got another lovely little wood box that I believe I’ll use for telescope stuff. Solid wood, even (pine, but still; dovetailed joints, etc). Too small for camera stuff, but the top compartment would hold all my telescope lenses and such nicely, with the bottom for other misc. things. $10. Busiest estate sale I’d ever been too; I was there an hour early and there were 30 ahead of me; by the time they opened up, another 60 behind.
