The OM-1 has a setting for using Focal Plane flash bulbs to synchronize at any shutter speed up to 1/1000 second. I was wondering if Olympus made a bulb flash unit. What types of bulb flash could be used. GE made #6 focal plane bulbs and Sylvania made #26 Focal Plane type bulbs. I was wondering if anyone had information about this.

I'm sure the original poster has gone on from this question. But if any one is interested. My recent investigations into the OM Flashphoto Group lead me to a picture of the OM system from the M-1/OM-1 era that had pictures of some pre T flashes. I found info on what I think they are. One is a Olympus Flash CL which uses AG-1/B flashbulbs. The other is a PS-100G. They both were used with the Pen cameras. They are both horizontally mounted. Have found one of the Flash CL's, still looking for the PS-100G. The PS-200 and PS-200 Quick are mentioned in the OM-1 Om-2 brochure. One of the system pictures I have found includes a black horizontally mounted flash that I have not identified yet. It is interesting that with the introduction of the OM system there was not a flash photo system until the release of the Quick 300 and 310. All the other "groups" were mostly complete at the introduction.

Thanks for the reply Ron. Those are the same as my own conclusions. I have had to look outside of the Olympus made products to find a more usable approach. I have been using a Graflex flash bracket and a Graflite connected to the PC socket on my OM-1. Using Focal Plane bulbs such as the GE #6 or #6B or Sylvania FP 26 or Sylvania FP 26B allows the camera to use flash bulb at any shutter speed up to 1/1000 second. Just make sure that the selector control at the PC socket is switched to the FP setting. This gives a result that is like using the F-280 Flash in Super FP mode with an OM-4T.

Looking forward to trying bulb flash with my early OM's .
