Hi all
I am trying to find the right bulb to go with a CEYOO flashgun and a iiig camera.
Could someone give me some guidance as to what is the right bulb to try to buy ?
Many thanks
Ian

IIRC they have a screw mount base, but were usually used with a screw-in holder for one of the common smaller bulb types. Both holders and bulbs come in three or four variations, it might help if you could post a photograph of yours...

Hi,
This might help:-
If not a screw thread, Edison screw btw, then they usually take the one bottom right. Blue for colour film and clear for B&W. Above them top right is an adapter with and without a capless flash bulb in it.
The capless bulbs for the adapter are the type in the PF1B box. The others are also capless but I've not seen an adapter for them.
The diameter of the adapter and the metal base of the big blue bulb is about 14 to 15mm.
Regards, David

Are you looking for display material or actually shooting with the CEYOO ?
In the hey-day of the CEYOO and the III-g / early M cameras, bayonet-base bulbs would have been most common among amateur photogs, for cost / space reasons .
Now, if you're trying to shoot flash photos in the 21st Century with this rig, read-on, MacDuff...
If I remember correctly ( all my Leitz blitzlichthalter are in storage...
),
The CEYOO will take the following:
"Edison, medium screw base"
"Bayonet-base" - with adapter "mast" furnished with CEYOO - places the shorter bayonet-base bulbs at the optical center of the reflector.
That's it for the official CEYOO as it came from E. Leitz.
But wait, there's more:
After the introduction of the "M" series bulbs and then the all-glass AG-1 bulbs, various suppliers came-up with adapters to use these bulbs in a standard "bayonet socket".
Dralowid posted a photo of the bayonet adapter "slug" to use the all-glass PF-1 bulbs, also known as "Vacu"... the "bayonet to M" is very similar, except that the center of the adapter is configured to accept the M-base bulbs.
I think somewhere, I have AG-1 > M and /or AG-1 > Bayonet adapters...
So... it is possible to fit almost any type of flash-bulb into a CEYOO and make it light.
I used this trick with a 1930's black & nickel Leitz "blitzlichthalter" flash-gun and a 1934 Leica black III which had been fitted with a PC flash connection ( fixed sync ), and using the "M to bayonet adapter slug", used M-3-B bulbs. It worked well, except that most of my pics were over-exposed. That's an operator's error.
I went with using M-type bulbs, as I have quite a supply of them.
Now, as far as getting the correct synchronization goes, that is a little more complex.
Does the III-g have an adjustable flash-sync dial ? If so, you can use almost any flash=bulb that will fit in the gun.
Be forewarned if you decide to try a big "Wabash" type Edison screw-base "Press" bulb - you might "cook" your subjects !

Hi,
Isn't this a VACU? It needs a special shutter speed dial on the camera.
I should have fitted the shutter guard from the camera on the VACU before photographing it...
And this shows the adapter and a fairly modern bulb beside the old ones.

David - you are correct, that widget was yclept "VACU" by Leitz, but I think there were also some all-glass bulbs in the early '50's ( like your PF-1 ) that were called "Vacu"... I have a couple sleeves of them somewhere...
I will try to dig them out...
Update - what I was trying to remember were Osram "Vacublitz" ! XM-1 / XM-1B. :bang:
David- you are quite correct: plain-old "VACU" is pure Leitz.

Hi,
Thanks for the link; fascinating.
Would you believe I got a shoe box of those large bulbs at a car boot sale for a pound? Sold most of them on ebay but keep the best little box of 5 or 6 and have it somewhere in the heap.

I have a couple of the Edison-base bulbs, my favorite is one with crumpled metal-foil inside. 
I save those for display pieces with my old Speed-Graphic press-cameras...
I'm too chicken to fire one off !
Best,
Luddite Frank
