What are these: Canon Baseless Adapters, PH and AG?

[Punkinhed7]

Got them in a whole grab-bag of old goodies recently and am having trouble figuring out exactly what they're for. Any help would be much appreciated. Thanks

To adapt flash bulbs without metal socket, but just bent over contact wires, to a flashlight that was designed to accept bulbs with metal socket.

It would help to have a picture I think.

What you have are adapters for a Canon B-C, or bulb/capacitor, type of flash unit designed to be used with their LTM rangefinders and Canonflex SLRs. These B-C flashes normally use flash bulbs with swan type bases, such as the Press 25. The adapters allowed for the use of smaller, baseless PH or AG type bulbs. I know that these adapters are compatible for the later B-C units (Canon Flash Units V/V-2/V-3), but I don't know if they will fit older models. For more info, take a look at the scan of the Canon Flash Unit V-2 manual on Mike Butkus' site:
