Fomaspeed 313 - A variable contrast resin coated paper - If it is the same emulsion as used on Fomatone papers, it should lith. Being an older batch, you might hit lucky in that it contains some cadmium. The best thing to do is mix up a small batch of LD-20 (or what ever your lith developer of choice is) and try it.

Of course, if you're in any doubt, you could always send it to me for testing
