Efke KB100 is the older type of film with thick emulsion. I have "Das Rolleiflex Buch" from 1938 and it has a recipe for "Metol- Hydroquinone-Borax developer" that is the same as D-76.(posted 8674 days ago)I would use the Efke KB 100 and develop it in D-76 1+1 (9 minutes 20 C)
For the best 30's result I would use a camera from that period with uncoated lens. My Balda 35mm with Schneider Xenar 2,9/50 is great for that! :-)
T-Max films all have T-grain, and will not give the wanted results.
