Leica lens accessories

When putting the photographic archives of my former collection in order, I re-discovered quite neglected accessories like these diaphragm- setting rings : the  first and best known is the VOOLA, the diaphragm setting ring for the Elmar 5 cm when equipped with A36 filter (two first photos). But there are also the VALAU and subsequent (1950) more elegant VALOO (at left on the third photo) for easily actuating the 5 cm Elmar's diaphragm when the lens was used on an enlarger. In fact, the VALOO was more utilized as a hood for general use. And finally, the VTROO - illustrated on second row and with two different engravings on the last image - served as aperture setting ring for the Summicron 50 when mounted on Focoslide.

The diaphragm- setting rings are quite interesting. This is first time I’ve heard about them.

Interessant en nuttig : als ik verzamelaar en regelmatig gebruiker was (Inclusief vergrosser), was ik gebruiker van die kleine dingen. Groeten van een (waals) belg levende voor meer dan vijftien jaren in Portugal...en die "onze" tweede taal niet  totaal heeft vergeten.

Pierre, thanks for sharing material again from your former collection. Last year I found the VALOO and bought it, which was then new to me. I didn't know about the other items you now show us!
