I have my 1960's Asahi Pentax SV loaded with some 'back to front' Fuji Super G 400 outdated to try this 'RedScale film process'.
My 1971 Pentacon Six has some 2001 outdated Kodak Porta 400 NC in it but the weather is far too grey now to go out with it.
My 1980's Canon AE1 has a short length of Ilford Delta 400 in it .
