This is supposed to be some kind of shutter synchronization/fine tuning device.

Can anyone tell me who made it, how to use it, or what it works with? Any

information would be greatly appreciated.<img

there were 2 similar devices made in th early 1950's

 

one was an adjustanble pliunger that screwed in the cable release socket and had a electrical socket that went to the flash.

 

the other was spring loaded and had no plunger, when the shutter was fired the spring pushed the internal pin down and fired the flash.

 

I used the plunger type on my rolfix folder as the pc contast was wobbily. cords were thicker and heavier then.

 

this pictured device is as the previous poster said.

my synchronizer was a 1/2"hard rubber tube with 2 1/16" tubes drilled thru.

 

the plunger came down and shorted the two contacts.

the cord had 2 pins that slipped (loosly) in the tubes.

It was wartinme and the tubes inside were poorly plated and needed to be buffed with an eraser frequently.

 

the tube going to the cable release was threaded and had a set screw.

they sold flashlight bulbs in a flashbulb socket so you could test and set up the synch. it did not work very well.

batteries leaked, what a mess.
