Adox NP-27: Anyone use it?

Hi, all -

I've procured some 10x12 Adox NP-27 for use with the project camera when the bellows are replaced. All I can gather on this film, though, is that it's ISO400. Nothing on the massive dev chart on it, and it's too precious to experiment with on developing times in HC-110.

Now, at 10x12", I expect that even ISO400 film is going to be essentially grainless. But has anyone got any real-time experience with the stuff, or know how it behaves with HC-110?

Thanks for any ideas.
Scott

That's Orwo NP 27.

It's a quite grainy film,so I recommend use Adox Atomal/ATM 49 (same as Calbe a49).
