A rather mild push (much less than a full stop) often helps older films like this. Also possibly some additional anti-fog additive -- if you're familiar with how it interacts with your developer in general. Depending on the importance of the films (sounds like you have no idea, which means low in general), you could do "clip tests" to determine optimum development at the cost of completely ruining some frames. In the darkroom, clip off a couple frames from the film and develop just them, examine to see how they look, repeat if needed, until you determine how to process the remaining part of the roll. Of course you can get fooled by badly-exposed frames that you happen to test, too. I'd say not worth playing with in this case. -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com/> <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
