1947 Dupont Defender films data sheet

I'm finally getting around to running tests on some of the really old 4x5 films I've picked up along the way. Most of them are sealed, so still have the data sheets inside the box. I'm still in the midst of all that, but I did run across one box of film with serious "vinegar syndrome" - the film sheets were shrunk down to about 3x4 and were a gooey stinky mess. I've had to scan that data sheet right away, so I can get the putrid thing out of my house! The film was Dupont Defender Arrow Pan, with a use-by date of 1-49, and a revision date on the instruction sheet of 9-47. There are several developer formulas included ( 53-D, 4-D, 4-DR Replenisher, and 2-D Pyro-Metol ) and I know how folks around here love old developer formulas, so I hope this sheet will be of some use to someone.

The good old days.......

Thanks for the reminder of my early days in photography. DuPont films were the easiest for me to obtain during WWII, and I use a lot of it. For 35mm the only film usually available was Dupont Superior, No. 2 in 27.5 foot bulk rolls. Weston speed 50. The sheet films were not as easily obtained so one had to get lucky and be at the store the day the shipment arrived.

Searching for info on DuPont Defender film, I found this thread.

I have an unopened, sealed box of DuPont Defender X-F Pan 4"x5" sheet film.

The box has the following notes:

Dimensions: 4 BY 5
Pieces: 24
Use Before: 11-48
Emulsion Number: 6495 7238
Ref. No. 5803

Non-Halation -- Safety Base.

Price marked as $2.58.

Came with the Graflex Pacemaker Speed Graphic kit that I recently acquired.

Dang, I was hoping that it would give the formula for the Defender/Harvey 777 developer ;-)

After WWII there was a lot of DuPont/Defender film available as surplus. I remember buying 100 ft rolls of 33mm for a dollar each.
