As the only available 127 black and white film, I think it's safe to assume that most of us are shooting Efke 100 most of the time (Maco UP100, and Jessops is rebadged Efke). I've therefore collected together some dev times for Efke 100. Most of these have come from other sources, and I've listed these sources, so you can refer to them for more info.
Unless noted times are for standard inversion processing at 20 degrees C. I've included a film speed where one was noted in the original source, otherwise assume a speed of 100.

I've added a comments for Econtol and R09 - the only two I've used. I'd welcome any additions or other comments. Remember these are only a guide, and should be adjusted based upon your own results.
Finally, Efke use a particulary colourfull anti-halation layer. A 1 minute pre-soak with water is recommended to remove this layer, and prepare the film for developing.
