Does anyone know where I might lookup frame markings? The only markings on this bulk roll of old B&W 35mm other than the frame numbers (5, 5a, 6, 6a, etc) is the code "B 364." Cannot find it listed anywhere... Thanks!

So maybe I'm confused here - I assume I have a good amount of base fog here - might try to use som benzo - but how can I tell underdevelopment from fog? Thanks!

Thanks! I shot this at 100 and developed with D76 at 1:1 for 8.5 minutes. So I will try another strip with longer development time and see what I can get!

Hi - Im working on a project shooting panatomic-x in a leica IIIa to recreate old family images from the 1930s and 40s. Does anyone have a source for rolls/bulk rolls of expired pan-x? I missed out on a bulk 100' roll on eBay.... Thanks! Darren

I have another unknown roll of bulk b&w film. I developed a test strip - any ideas about what it could be? I can read something like "B 364" on the right side. Thanks!

Thanks AJG! That is amazingly cool. One more film stock I just tried - super foggy - but it says "B 364" on the sprockets. Any idea? I shot it at EI 100 and developed at 8.5min in D-76.

Hi! Circling back to this topic. I cut a bit of my mystery old film and spooled it on to a cassette in the dark. The film is white - any thoughts about what it is / if it is trash?

Great, I'll give it another try, perhaps with anti-fog additive. Does this seem consistent with very old Tri-x? what is a guess on what im shooting here? for what its worth, the color of the pan-x and 2496 emulsion in the picture above is very different than this film in the bulk tin that was marked tri-x (but who knows what it is). Thanks again - the mystery of this film may not be worth it, but im hooked on getting it figured out!

Right, I can try another simple scene. Thanks. The film seems a bit fogged, yes? here it is next to a bit of HP5

Ok so I developed the leader until the darkness of the back and front equalled out and I got around 6.5-7 minutes. Then I took 8 frames from 50-800 EI and the developed at 7min D-76 1:1. Frames for 50 and 100 are closest to ok, the 200 and on is very thin (light negs) to nothing. Here are the two at 50/100. Pretty grainy quick scan - could this be old Tri-X that now wants to be shot at 50/100? The canister says Tri-x but this was possibly either Panatomic-x or 2496 as the box I found had some bulk rolled films labeled as such. As expected, no frame markings about what the film is. Thanks! T

Thanks Rodeo Joe - that helps!

Wow, thanks. This will be a project to diagnose. I'm not sure I understand the second phase here. Cut the leader frame off and in the light see how long it takes for the front and back to look equally dark? when I have the time, I assume that I can guess what actual speed film I might have here. I dont have a way to measure density. All this for 50' of unknown film, but im so curious what it is! Also - just to be clear - to see the frame markings on film do I develop or will they appear if I clear a bit of film with fixer?

Thanks that is super helpful! I'm hoping this old 2496 works, and also the Panatomic rolls. I have this tin of sealed positive film from ""Superior Bulk Film Co." out of Chicago - If I cut off a small bit in the dark and put it into some developer will I see labeling on the sprocket holes about what film it is?

Thanks! It helps a bit. Still not sure what I have here. If it's rated at 125, and it's who knows, 50 years old, what a good approach might be.

Hi! New member here. I recently acquired a box of rather old film stock. It includes some bulk rolled canisters of Kodak 2496 RN 125, and some Panatomic. I want to try and shoot these films - any advice on how to develop them in d-76? Also found in the stash: unopened Lumipan 100 in med format, and a canister of bulk film from "Superior Bulk Film Co." from Chicago with no other markings... Thanks!
