In the Laney book on P365 there is more...
CAVOO comes in versions A/B/C/D/E/F
COOIF is a spare synchroniser for CAVOO engraved on the rear edge with a symbol rather than Vacu.
CMVOO are spare 'cam' shutter speed dials for various cameras.
I have come across (and replaced) these cam dials in the past but never realised they were Leitz. Always assumed they were after-market.

On a trip to Denmark the other year, I picked-up two Leica III-c cameras, one a beautiful conversion to -f Black Dial + Self-Timer, and the other, a stepper that had been painted black, which has a CMVOO sync dial.

Thanks for the information Michael.
Page 114 of 41st edition of Focal Press's "Leica Guide" gives information about the various speed dials and their application to screw mount body s/nos.:
Dial A: For s/nos. 215651 to 226000 (earlier s/nos. can be done with adjustment).
Dial B: For s/nos. 226001 to 360000
Dial C: 440001 to 460000
Dial D: 360001 to 392600
Dial E: 392601 to 397000
Dial F: 397001 to 440000 plus 460001 to 520000.

Not at all, I hate flash even though I have an M6TTL (whose SF whatsit I have now sold)!

LOL... I prefer existing light or studio lighting, but there's something about flashbulbs and flashguns that really hooked me as a kid...
And I also have a weakness for convoluted contraptions, so things like the Leitz Vacu are right up my alley...

Hi,
Oh dear, I agree with both of you. I couldn't afford flash bulbs very often when I was at school and so never really got into the habit. Later on in life I could afford old, interesting second hand cameras and so got into the habit of buying them and their gizmos.
In the late 50's or very early 60's I managed to afford one of the early electronic flashes (designed and sold from 1952 or '53) but sold it years later and am now looking for one...

I know I have a box somewhere of bulbs, flash guns and even electronic devices that came with various things that I have bought over the years. All junk I should imagine but I did like the reflectors that open out like a flower...

Flash gear ( and other ancillary gear ) can be just as addictive as Leicas themselves. 
When I was born (late 1960's), my Dad bought himself a second-hand Nikon S. Somewhere along the way, he also acquired an Acura "Bouncemaster" flash gun, of 1960's vintage. It had one of those fan-flash reflectors, which fascinated little me to no end.
Interestingly, that flash only had a coax PC connection, and Dads' Nikon had the early Nikon bi-post connector, so the flash was no useless with Dad's camera. It still provided hours of entertainment for me.
About 10 years ago, I happened to win a big box-lot of assorted Leica flash and other stuff from KEH, who I guess was cleaning house of some oddball "junque" that just wouldn't move. It came cheap.
Contained maybe half a dozen CHICOs and CEYOOs, plus sync cords, etc.
This is where my 1930's "Blitzlichthalter" came from ( in its red Leitz box! ).
Lots of goodies in there...
My "grail" items of flash equipment, besides a complete Vacu synchronizer, are any powder flash-guns from the pre-bulb era.
I also got hooked on early electronic flashes... one favorite are the early Braun "Hobbyflash" outfits, with their black battery-pack on a shoulder strap, and "gun" type flashholder that looks very much like a 1950's bulb-flash. I have three or four of these, all work on line-current, but I can't get the vibrator circuit going to charge off dry-cells.
Also have a couple Heiland / Honeywell "potato masher" Strobanar units from the early 1960's...
I'm a veritable magpie for oddball camera gear...

For the latent arsonists amongst us, this is fun...mind you I never dared light it and didn't like the idea of magnesium in my pocket!

It came in a box with an early Leica I and some other interesting bits and pieces most long since sold.

Hi,
I inherited some flash paper but didn't know what it was until I started collecting and read about it in a magazine. It does what it says on the tin.
EDIT: OMG, we've formed an arsonists' sub-group...

That's pretty darned nifty ! Never imagined something in such an elegant little package.
I would not want to tote it about on my person...

I thought it might be fun trying to explain it to security at an airport, but maybe not.
PS. Just found one single flash cube, where on earth have I put the rest of the flash junk? Maybe my cupboard has become similar to the one in Narnia and there is now a snow covered glade somewhere full of mysteriously shaped rotting batteries, mouldy camera cases and filters that will never ever fit anything.
