Still feeling run down (sleep helped, but I probably need
more) and am now battling a headache. Looking around to see
what I can get done without pushing myself too hard.
I was recently given an old photoflash. One that takes
flashbulbs. (I've wanted one for a while -- some of my older
cameras have an "FP" connector, so once I rig an adaptor and
find slow-burning flashbulbs, I'll be able to shoot with flash
at any shutter speed as long as I'm using an old enough camera.)
I popped it open to see whether the "Kodak 'C' Photoflash"
batteries described on the sticker on the back of the reflector
were just ordinary C cells. I was surprised to see that there
were batteries still inside. They're the size of modern C cells,
labelled "Bright Star Photo-Flash Battery", but have no voltage
marked ... I'm guessing they're just C flashlight batteries
labelled for sale in camera stores. But that's not what amused
me enough to write about them. What got my attention was that
they have an expiration date on them like the name brands have
started doing recently. They're marked, "FOR BEST SERVICE USE
BEFORE 3-57".
There's surprisingly little corrosion, for something that's
had batteries in it for nearly half a century.
(The electrical connection is a pair of posts sticking out
the side of the unit. They're spaced the same as the holes on
the side of my Argus rangefinder (which, because it uses a leaf
shutter, should be able to shoot flash at any shutter speed
anyhow), but one post is threaded and extends all the way through
the device to a knob on the other side, and the threaded part
is too wide to fit into the hole on the Argus. Anyhow, my plan
is to use the cable from a broken PC-hotshoe adaptor and connect
the wires to the studs with alligator clips to start with and
do something more permanent later. That's the easy part.
Slightly harder (but not by much) will be the mechanical mod to
attach it to an SLR (I'd prefer not to simply stretch rubber bands
around camera and flash). I've got a few ideas for that.)
