for the possible Wonder Light battery?
Steven Johnson, Shiloh, IL
I'm looking for some information regarding a "Wonder" rear bike light. L
ooks like a little flashlight with a red lens cover which fastens to the
left rear dropout of a randonneur bike; e.g., Singer, Herse, etc. I won
one of these on the 'Bay, but I can't locate a battery for it. It looke d initially like it would accommodate 2 Size-C batteries, but the batter y case is slightly too small in circumference to handle Cs. If there was
a Size-B battery, it would probably fit :^) Perhaps maybe our European counterparts might be able to point me in the right direction. Any maste rs of battery esoterica out there?
