Probably not helpful but the Me P8 also pops up in relation to the Bf 109L project and Me 410.
The Me P8 was a variable pitch, three-bladed propeller with wooden blades. These 3.2 m diameter props were built by the Messerschmittwerk Kematen, a forced-labour factory (aka Messerschmitt-Zwangsarbeitslager Kematen) near Innsbruck in the Tyrol.
