By "sleeve" I just mean an inert plastic tube that keeps the 357 from rattling
around in a space made for the bigger 625. If your camera has been modified
to allow for higher voltage batteries (usually by wiring a diode into the
circuit) you have no need for the Wein cells (1.4V) or the CRIS adapters
(which also drop voltage).
