GAF 2955 Black and White reversal film

Hello there,

I'm quite new to this forum. I've shot a large number of 16mm Tri-X rolls over the past few months and I've recently come into possession of some GAF type 2955 black and white reversal 16mm film. I can't seem to find any development charts or chemicals used to process this type of film, unless it's the same used with Tri-X: D-19 D-76 D-96 etc. I though I would play it safe and ask if there is anyone who would know better than I would about processing this type.

Thanks!

From its age this film may be orthochromatic If you can establish that then you can develop it by inspection. Remember to judge the degree of development by looking at the base side of the film not the emulsion side.
