Fash side rail/PC outlet?

I'm not sure there would be much point, if you are thinking of using a modern electronic gun - the side rail is designed for flashbulbs ("M" synch) which take a few milliseconds to reach full brilliance. This is normally timed to coincide with the shutter being fully open. If you initiated a thyristor gun at the same point, it would be all over in a couple of microseconds - possibly before the shutter had even half opened. This is why electronic guns need "X" synch - you sometimes see both on cameras from the 50's and 60's when buth types of flash existed side by side.

Of course, if you had a stock of PF1b's and an old gun with a PC plug, the idea would fly.....
 
Thanks John for your quick reply.
My question should have been more specific.
It applies to a Canon 1VSb2 and a Canon 1VS2/IIS2.
Best regards,
Pyrs.
 
Those cameras both have X sync (all IV's do) and I saw one of those adaptors for sale at Pacific Rim when I had my IVSb but never had the $$$ - not much just broke. Just browse their for sale stuff.

It may have been rail to household plug but if so, Paramount offers the appropriate cord to go from household to pc.

The Canon Self-Extension Adapter is much more common than the PC adapter stesm posted, it goes to "Edison" (household) socket. It's fairly chunky in size.

I have a Canon side rail adapter made by Minicam, which went to some screwy two-pin socket they used. I took it apart, and stole a PC socket from a parts camera, drilled a hole in the bakelite, glued the socket in, and soldered it up.

As for X-sync, most, but not all, Canon side-rail screwmount cameras have X-sync. Canon was proud of offering flashbulb and X-sync via one external connector, and had a patent on their clever design. Some of the economy models only have flashbulb sync. (Value pricing 1950's-style.) So long as there's red X's on the shutter speed dial(s), you have X-sync.

However, the only flash I've used with my Canons is 26B bulbs in a Canon Flash Y. Really makes an impression on folks who grew up in the "teeny flash on a point-and-shoot" era. Ka-poom!
 
the favorite PX store bottomloader Canon seems to have been the IIF, this offered flash bulb sync only and this makes sense as to most amature photographers in the early to mid 1950s, flash photos meant flashbulbs.
 
Here are some pics of the three adapters that I know of that slide onto the side flash rail of some of Canon bottom loaders.
  1. Canon produced PC adapter in box
  2. Minicam PC adapter
  3. Minicam two hole version (not sure of name)
There maybe other manufactures that have produced adapters but as of yet I have never seen one.
