Help identifying Leica items

[somprasad]

I am working through some Leica bits I acquired some years ago, it has items which I am not sure of the exact designation,and would like to catalogue them properly and also see if there are some I can use for various purposes.

So I am putting a few queries here, I appreciate the advice from Leica knowledgeable people on this forum.

I suspect this one has fits in with the visoflex system, but not sure of exact model and function.

Inscriptions on the sides are

(In white lettering) CR 1.5 -OL
In black - Antireflex
VI LIFA Germany

No threads, so must slip into a slot somewhere I presume

Any ideas? Thanks for all input.

And also, this odd Leica filter couple:

These filters have no thread, and are stackable,

Thanks for help in identifying, much appreciated.

The first is a colour balancing filter, from hot burning halogen light (3400°K) to tungsten film (3200°K) - probably mid sixties to late seventies, as that light type was most popular in the boom years of 8mm home cine, but these filters also were in use for conversion from earlier short-burn "photo" tungsten lamps. Not a Leitz filter by the way, but made and branded by Lifa - a major filter maker, but a minor brand, as they mostly acted as a OEM for German camera makers and camera store chains.

The second is a regular Leica A36 push-on filter, light yellow by the looks of it.

Thanks a lot, I wasn't aware of push on filters for Leitz
