Thanks for the info. That’s a huge help. 😃

There is a heavy Vinegar smell on these for sure. They were stored in a wood trunk for god knows how many years. I’m thinking this is end of days for more than a few of these reels.

For now they are sitting in my house at room temperature and I hope to get to them this weekend. At the very least I was planning to separate the Vinegar smelling reels from the others. Hopefully a few of these can be saved and scanned before they go completely.
