MMW (Mitteldeutsche Metallwerke) built in 1944 the Kalkert Ka 430 .

https://www.secretprojects.co.uk/threads/kalkert-ka-430-cargo-glider.5359/

Dipl. ing. Albert Kalkert was born in Thuringia, Weimar Republic was a prolific airplane designer.
During the 1920s, he designed and flew a low-wing, cantilever monoplane powered by a mere 100 horsepower, but capable of carrying a pilot plus 4 passengers. The manufacturer was "R ... something."
Kalkert started designing for Gotha during the early 1930s. His first Gotha design was the popular (1,100 built) Gotha 145 biplane, light trainer. Then the prototype-only Go.146 light touring airplane, then the Go. 147 experimental, parasol flying wing (similar to the Westland Pteradactyl), Go.148 light twin, Go.150 two-seater sport turned military trainer, followed by the Go. 242 assault glider, Go.244 motorized transport variant and finally the Ka. 430 assault glider.
Finally, the Go.345 pulse-jet powered cargo transport.

As for MMW:
Founded in late 1930s, as repair shop for Heinkel aicraft. 1940 Kalkert became employee, and after the renaming/reorganisation the company starts manufacturing Focke-Wulfs Fw 190 A-8, A-9, D-9 and Ta 154 A-4. Kalkert Ka 430 Seems to be the only "new" product of theirs. In 1945 the Soviets dismantled the factory as a victory prize and moved everything back to the USSR.

Mr. Otto Onigkeit designed aircraft after WWI ?.
Otto Onigkeit (Magdeburg) built before the first world War four monoplanes .

After the War , in 1921-1923 , he built a man-powered plane with crashed at it first taking off in 1923 . Otto Onigkeit was heavily injured .
In 1924 he built a little biplane which he flew until 1935 .
In 1925-1926 he built a monoplane .
At last , in 1938 , he built a new man-powered which flew several times .

Here , the 1924 biplane and the 1938 man-powered monoplane . I don't know pictures of the first and third planes : I would be glad to see them ...

here is a motorglider,designed by L. Otto.
Your picture shows a sailplane which could be a Berlin Segelflugverein Luftikus .
The Ott Dynamikus was shown at the Vergleichsfliegen in Rangsdorf (Nr.5) (13-17 august 1937) , with ten other light planes .
It was , like the Saurna-Jeltsch Milan and the Sombold Kormoran , similar to the well known Schneider/Grunau Motor-Baby .

Thank you my dear Richard,

has anyone a drawing or picture to F. Papenmeyer P 1 Monoplane ?,

Ingenieur F. Papenmeyer worked among other at the Flugzeugbau Kiel as designer. In the beginning of the thirties he designed a lowwing monoplane with a radial engine and a rectractable undercarriage for Graf Reventlow. The plan was to have it ready to the Europa-Rundflug 1932. It was probably never finished.

From an unkonwn source, mayby FliegerRevue.
"There are no photos or drawings of the Papenmeyer P.1. Allegedly it should have been quite similar to the Bäumer "Sausewind", therefore a three-sided plan of the B.II."

Papenmeyer designed the P.1 for Hubertus Graf von Reventlow-Criminil.
Graf von Reventlow , after having got his pilot licence in April 1931 , bought on the 7th May 1931 the Sausewind IV D-1414 . He crashed on the 14th of the same month . The pilot was not injured , but the D-1414 was totally destroyed ...

From generic sources ...

The Göken (Cuckoo) was designed in 1930-31 by the German flight instructor, Willy Pelzner (01 June 1900-23 July 1977). The Göken was assembled at Pelzner's flying school at Hammars Backar (east of Ystad) - by then, his original partner, Greve Douglas Hamilton had departed. The open framework fuselage was constructed from welded steel tubing ... alas, no other details.

In 1931, Pelzner formed the Flygtekniska Försöksinstitutet Aeolus (Aeronautical Experimental Institute Aeolus) with Lennart Hemminger. Together, they designed the TP 171 light biplane. Structure was veneer-covered wooden wings and a fabric-covered, welded steel-tube fuselage. Power was by a 24 hp Hirth 2-stroke engine.

From the Bruno Lange books : Sächsische Flugzeugindustrie GmbH (Dresden) (SFI) Gammelin Ga1 "Kombinations-Flugzeug"

Two seater , the 9,70m wing can be enlarged to 12,95m , and it can get side windows to close the cockpit becoming then sport/school/travel plane .

Vmax 175 km/h . Hirth HM 60 R-1 engine . It was tried at Rechlin in 1934 .

Picture : from Herr Karlheinz Kens :

The Göken was assembled at Pelzner's flying school at Hammars Backar (east of Ystad) - by then, his original partner, Greve Douglas Hamilton had departed. The open framework fuselage was constructed from welded steel tubing ... alas, no other details.

In 1931, Pelzner formed the Flygtekniska Försöksinstitutet Aeolus (Aeronautical Experimental Institute Aeolus) with Lennart Hemminger. Together, they designed the TP 171 light biplane. Structure was veneer-covered wooden wings and a fabric-covered, welded steel-tube fuselage. Power was by a 24 hp Hirth 2-stroke engine.
Here are two photos & a data table from "Svenska Flygplan" by Lennart Andersson.
The first is described as an ultralight with 10hp ABC from1931 - so this is The Göken (Cuckoo).
The second is described as a biplane from 1931 with 24hp Hirth - presumably the TP171.
There is also a table of Swedish light plane specifications - the Pelzner Biplan with 24hp Hirth would then be the TP171.
The Google translation for the accompanying text reads:
"Willy Pelzner's business as a designer and innovator for the construction of aircraft is not fully investigated. Several projects were built without the usual control but with the good memory of the authorities. One example is a biplane with a water-cooled Hirth engine of 24hp. The plane was built in 1930-31 and would have been on ILIS-31 in Stockholm. The plane was not registered, but surveyor Kjellson admitted flying in the immediate surroundings. On the first test flight in the spring-31, a fence stood in the way. Around the same time, a 10 hp motorized hang glider was underway , the end result was a small aircraft reminiscent of the early ultralight aircraft of the 1980s."
