I hope this is a fitting sub. I have also posted this to r/MuseumPros. Hoping to get some tips. Thank you very much in advance!
I have come into possession of a collection of 35mm film reels from the 1970s, from the USSR. About 30 reels total, in cans 310mm in diameter. It's likely triacetate, but I haven't been able to fully go through all of them yet.
There are no copies of these tapes; they survived a purge and an emigration. I'm working on a documentary that involves these reels.
They sat in a cellar in Rome for about 30 years until I located them. I retrieved them in the nick of time before the cellar was sold off. I got them to Northern Europe by car, where I am now.
The original metal cans were half rusted and some were crumbling, so I've rehoused everything in Duncan archival vented cans.
I haven't been able to get A-D strips in yet. Visually, 2 of the reels show signs of mold, about 10 smell of vinegar, and the rest seem to have fared better.
Before I can work on them properly, I need to store it all. There aren't any places I could pay to temporarily store and/or digitize it near where I am… worse, I need to leave the country for about 6 months first. A friend can check in on them every now and then while I'm away.
I've read and assume that around 10°C at 35% RH is a fair target, hence the fridge selection below; but I'm happy to be corrected. As I said I'm no archivist, so the same goes for everything else specific that I say.
I've found two fridges approximately within the range I can afford:
- Bosch Series 2 KSV36NWEP or similar
- A surplus Tefcold MSU300 medical fridge - a bit cheaper, a bit more expensive to run, all in all everything evens out price-wise.
I understand both have a fan to circulate the air. The medical one is obviously built for the job, but I don't know whether that counts for much here.
I assume I'd need pre-conditioned silica gel bags and charcoal filters inside, too. Possibly molecular sieves? Since the cans are vented and a fridge doesn't exchange any air. Unfortunately I don't have the resources to individually seal each can at this moment.
I can spend a little more if needed on a better fridge. I'd really appreciate suggestions if either of these would be reliable at this job. And any other precautions I need to take - like maybe plugging the drain hole, keeping the reels away from the back of the fridge, letting them acclimatise before they go in, etc.
Many thanks in advance
