Yes,
See below, the FP bulbs have a nice long plateau when they burn.  The 
OM2 has an FP setting that fires the FB ?10msec or so prior to
first curtain though X synch will work with a slow shutter speed.   I 
have a neat dookicky from John that locks it in place
so I don't have anymore untoward foul ups from the switch becoming  
inadvertently altered.
 I  see replacing these monster FB's cost a pretty penny.
It is promising that Dr. Flash thinks it may work in TTL auto.  The GN 
does vary with the reflector and shutter speed and I will fire 2 to 
three but only really
need to be sure I don't overexpose by much.  I will set it up on a 
tripod per the previous diagram from JK. He should look NE Mon PM and 
may perhaps spot
the ignition.
