Verichrome Pan test roll

I have 4 rolls of this 50 year old film. I wanted to shoot a test roll, so I know how to shoot the other 3. Shots turned out well. You should see the full versions, a very nice grain. I mixed up a special developer brew. to add more contrast. and I overdeveloped. I did this because films loose a bit of contrast after 50 years (I've been told).

The lines you see are my fault. I put the developed film.
on my radiator for 10 seconds and this was the effect. I always do this to dry it a little faster. Modern films can handle this. This one not.
