I think in discussions of old film processing the adding of a restrainer was 
not recommended.  There will be fog more than likely but a restrainer probably 
won't help.

a 7-12 minute development will probably be OK.

Subject: [pure-silver] Developing Univex ultrachrome No. 00 film
 
Hello all,

A neighbour recently gave me a box filled with old cameras and film.  Inside, I 
found 4 rolls of Univex ultrachrome No. 00 film and it is marked EXPOSED.  What 
information I have been able to find states that it was made in the 1940 by 
Gevaert of Belgium for Univex.  A label on the box says that it should be 
developed by 1949.

Since I can't let sleeping dogs lie, I want to try developing the film.  I have 
no idea regarding the film's ASA and no info is forthcoming on the 
Internet..... So....

Anybody have a clue as to the possible asa of this film and what would be the 
best way to proceed with development...  All ideas are welcome.  I have four 
EXPOSED rolls.    and I still have my 3.5 gal tank of stock D-76 which I was 
going to dump but decided I could develop the film by dunking it in the tank.  
Probably have to add Benzotriazole to the D-76..... how much per litre/gal?  
Anything else I can try?  I'll do one roll at a time, so I have 4 trys at 
finding the right combination to adequately expose one roll of the film.

Thanks for any ideas...

Cheers,
Bogdan K
