Wow very interesting. I work for the British navy, my grandfather served during WW2. It looks like your first example plate is of French ships flying the Tricoleur (a bit tricky to tell in negative and with orthochromatic film). The second plate shows some kind of celebration or party (possibly liberation!). There is an officer on the right and women having a good time on board. Important images that I would love to see. By all means print but I'd also suggest scanning at high res so that these can be digitally re-touched. I hate to suggest this but there is no practical way of repairing the damage other than this and I do think these merit sharing with a wide audience. You may be able to identify the ships from their numbers (if visible).
