I read that there are a few small operation services that do this, with the option to do only B&W for a better possibility of viewable results. Its always a shot in the dark with film exposed so long ago, you never know how it was handled, or left in what temps, or in areas of high radiation.
I somehow segued to film recovery whilst reading about Everest, and the summit attempt by Mallory and Irvine, and the possibility of recovery of the Kodak roll film camera they carried. There is a document written by a Kodak tech for the general handling of the camera and film if ever recovered. A very interesting read for anyone with a bit of time.
I just got a roll of Verichrome Pan in 620 dated from 1959. I'll shoot it in my Hawkeye Brownie. Also have a bulk roll of HP3 from July 1963. I bought it on a whim off eBay since that's my exact month and year of birth. Shot some at 25 and it came out alright!
"Well, my photos are actually much better than they look..."
Well I have several rolls of HP3 120 roll film that was exposed in 1952 and never developed! I did a clip test on one roll and managed to pull two images off the whole thing. It was badly fogged, the backing paper had merged with the film and had to be coaxed off, and I think it had caused a lot of chemical fogging. I will probably post a thread in the b&w section seeking ideas on how best to develop the other rolls. I also have some exposed, undeveloped glass plates from the same era.
