During WW2 the Germans captured many types of Allied aircraft and actually repaired some types for sale to Co-Belligerents and Italy. Others were transferred to KG 200 for clandetine use as aerial fighter directors and spy droppers (largely the B-17 and Short Stirling). At least one intact P-51 Mustang was repaired, examined, and flown and this led to a 1945 decision to produce a wooden light version of it through the Espenlaub Flugzeugbau. However, since they were overloaded with work and transferred to the GREISE I facility, the Kholba Werke which made German decoy aircraft was given the job. Their last-minute design called Kralle (Claw) was for a light-weight wooden version to be powered with available German engines (primarily the DB 605) and armed with German cannon (2x 30mm MK-108 or substitute 20mm MG-151/20s). The cannons would have 150-200 rds capacity each. Landing gear would be German too and would also carry German radios. Three different small scale models were built to study the design but no actual work was done on a full-scale mock-up and so no prototype was built either as Germany surrendered on May 8, 1945. The wooden models were burned.
