GAF 2863 5X7 film

The M&M Compact Photo Lab Index from 1977 shows two b&w sheet films: Versapan 2831 ASA 125 and Professional 2881 ASA 250. By 1977 2863 may have been discontinued. No color sheet films are shown. The 1977 Industrial Photography Gold Book of 1977 shows GAF sheet films on Page 107. It lists Versapan Gafstar in 125 and 250 ASA speeds. If you can find a Photo Lab Index or Gold Book from 1975 you might have some luck there. Whatever you have it is probably very fogged by now. Do some testing. You should at least be able to determine whether it's color or b&w.

thanks
