Hi all,

This is my forst post to apug.

I bought a few 35m rolls of b/w film called "ProGold" Bangalore in India where I live. Curiously, it is labelled NP22 and ISO 100.

ORWO used to make NP22 which was a 125 speed film.
This film looks bluish, which I have not seen before.
Also, after developing, the developer turns purple colour.

It also has a edge marking 2651.

Can anyone please identify this film? Does the number 2651 ring any bells?

Thanks in advance,
