I decided to get a mate for my Panda.
The new one on the left came with no chips in the case, but it did have about a twenty-five-year accumulation of cigarette smoke residue. Fortunately, I was able to clean things up fine with some lens cleaning fluid. I doubt the original owner was so lucky.
I'm going to try this custom viewfinder hood the next time I get out with the Panda. I'm thinking having two Panda will also let me load slow and fast film. Given the latitude of modern films, I should be ready for about anything.
