Only know they are German Made.

I have pics of a WMP Kit.

Here is 1.

I,d contact Sonor and ask if they know who may be interested in them. They may want them for their own museum to display German drum making back then.

Now I feel like watching Das Boot...

Lefima ist still on the market, but not as manufacturer of drum sets. They offer concert and marching percussion.

It is one of Germanys oldest drum makers, the link above might help to get some information.

The brand has no extended historic info on it's site... I've emailed them.. maybe I get a response :-)

Wow! That kit has some nice knockers on it...what are those coconut shaped things called?

The Coconuts are called "Temple Blocks".

Most trap kits are 20`s, 30`s and 40`s.

Yes, after researching today I think this kit is from the late 30's, early 40's.

Snare has the silk steel-wounded snares on it.
