There is an Alkline version of the 625, the PX625A, that has the exact same
dimension as the mercury 625.  However, my impression was that the MR-4
meter would not work correctly with 1.5V. I called Leica in New Jersey and
they told me that they can re-calibrate the meter for 1.5V. If it's only
off by 1/6 stop as you tested, then I could care less.
