Ansco is a brand name from quite some years ago. They made both B&W and color. Whether there will be a latent image left is questionable, because it's liable to be 30 or 40 years old. I *think* it's black and white. If it were very urgent to process it right this minute, I think I would go with D-76 or XTOL, with the recommended times for Plus-X or FP-4, since these are more similar to the older, thick-emulsion films than the newer stuff like T-Max.(posted 8196 days ago)Let us know how this turns out!
