I did a search for b&w 100 speed 127 film and found nothing. Seems 400 is still available. Does anyone know of a source for 100? I don't want to cut down 120.
I don’t see ReraPan in stock anywhere but they are always running out and re-stocking it so just keep an eye out for it. B&H, Freestyle and Lomography are a few good places to look.
Film for Classics at http://filmforclassics.com/ shows that they are still making a 127 film 100 ISO. black & white--B&H is one of their distributors, so if it isn't on their website try contacting them.
