The first thing to find out is whether these are ORTHO or PANCROMATIC. I assume they're ortho but best to check. If they are, you can develop them by inspection under a red safelight. When you expose them they will benefit from plenty of UV light. I'd expose a test one, develop it and see what you think. I've been using very old dry plates including Kodak P1200 and they all seem to be working well at ISO 5. I'm surprised these new ones are ISO 2. Light meters can't meter UV light so just use any meter reading as a guide for your highlights and go from there. Have fun with it.These arrived today and I'd be interested to hear any advice on using and developing them. I plan to tray develop them in HC-110 using a red safelight. I bought some MPP plate holders and plan on using my MPP MicroPress.
Hi Nas, yes they are orthochromatic so a red safelight is OK.The first thing to find out is whether these are ORTHO or PANCROMATIC. I assume they're ortho but best to check.

Great photos, I've bought some HC-110 as it seems to be the recommended developer. I just need to get some developing trays and I'm ready to go.I shot a box of 10 of these in half-plate size last year and have another box in 4x5 size waiting to be shot this year.
I exposed at EI 2 and developed for 6 minutes in HC110 Dil B, in trays under a red safe light. Since you can see the progress of developing you could amend the developing time if necessary.
My results are here:
