Dupont Arrow Pan development

[Kawaiithulhu]

I've got a dozen 5x7 sheets whose only notch code match I can find is for Dupont Arrow Pan. These sheets are in the holders and I don't know if they're exposed or not, but I'm going to try and see. I have no idea how these have been stored, but the case and camera involved are in great shape so not abused with high humidity but also not in cold storage.

I've got Rodinal, XTol, and pyrocat-HD available. Any advice on this WW2 era film stock, or just do the usual dilute and stand develop?

Thanks for any input!

I've always used (old, 90s or early oughties vintage) HC-110 Dilution G or H for very old film, on the basis of claims I read about it having a strong anti-fog property. Based on recent reading, of the developers you have, I'd suggest XTOL or Pyrocat-HD, diluted, as cold as you can manage, development time extended 4% per Fahrenheit degree below 68F, and a few drops of 1% benzotriazole solution added.

as cold as you can manage

I'd forgotten all about that idea! Probably what I'll end up doing, thanks.

I tried one sheet today. No latent image. But wow, this emulsion peeled right off the backing under just running water. I'm going to have to use Ilford method water baths just in case.

Might want to use a hardening fixer as well.
