Old paper junkies, can you help me out.

[Rlibersky]

I have some paper I would like to identify if possible. I’m sure it was manufactured for the military. Just mot sure when or what type.

Here are the particulars:

Kodak Chloride
Type: IX
Contrast 3
250 Sheets
10x10
US Army Spec.: 75-157-D
Stock# A.A.F 7400-59675
ENG. 18-524.300-500
Emulsion: 36689

I have made prints on this paper. Using Ultra-Black I get a brownish tone. It looks good but more like a grade 1-1/2. The paper is single weight, luster.

Well that what I got. I don’t have a scanner available at this time or I would scan the picture.

Any ideas of type and age?

I believe that the Kodak Chloride paper was used to contact print 10x10 glass plate negatives used in military recon. aerial cameras.

Thanks Do you know what era it might have come from?

Having a Mil Spec number is not a guarantee that something was manufacturered specifically or exclusively for the military. Usually these products were plain, ordinary, of-the-shelf products that the military chose to use. The only thing that the mil spec number insured was that the military was supplied with documentation on how the product was manufacturered. In case of a supply problem, this information would enable them to find another manufacturer. Thus, Air Force Developer Number 2 was just Kodak's DK-50 developer. If you look at the pertinent document you will find the formula for this developer.

Would the Type: IX give me what paper it was in the pertinent document then?

I doubt that the documentation will just state something like "this is Kodak Azo paper" or "this is Kodak Velox paper". What you may find is a description of the type of emulsion used to coat the paper. These documents are quit varied in what information they contain. For my example, the documentation does not explicitly say DK-50, you have to compare the formula given with Kodak's published formula for DK-50 to find the connection.

Okay. It would be nice to know. But then we can't know everything. Do you have an opinion on the vintage of this paper. If it was for a 10x10 ariel camera wold that put it in the WWII era.

 

[Jim Noel]

The paper was in use during WWII. It was used to print glass plate aerial recon photographs.
Since the need was for a fast printing contact paper, it was most likely Velox, rather than Azo.

It sounds very similar to the military Haloid Industro that I have in 10x10" dating to the 1950s. It's marked grade "2" but is also about a grade softer than Azo grade 2.

I have a roll of military paper made by kodak with an ink stamp that says:

INSPECT OR DISTROY BY OCT. 1979

See if you can find anything like that.

 

[Rlibersky]

No nothing like that. It was unopened when I got it. I think $23 on Ebay.

This accidentally go stuck in the wrong place:

"AAF" is a key. It stands for Army Air Forces, dating the paper to before 1947 and after 1942. By 1945, the Army was using Kodak Resisto (an early resin coated paper) for contact prints from aerial film, so this is probably earlier. The loss of contrast may simply be due to age. Resisto was similar to Azo, which is a simple chloride emulsion. This too may be an Azo variant. You might try some benzotriazole in the developer to see if the tone and contrast improves a bit.

We used to have a contct speed paper that was called AD back in the 1970 base photo labs. Don't remember much else about it.
