The B does stand for Bulb, but not 'flashbulb'.  The bulb they are
talking about comes from the old cameras that were triggered by a
pneumatic squeeze bulb.  There was a piston that screwed into the
trigger assembly, an air hose, and a squeeze bulb on the end of the
hose with a hole in it.  The photographer would cover the hole with
his thumb, squeeze the bulb for as long as he wanted to expose the
picture, then release his thumb to close the shutter.
