Need help with identifying plane for Wohlert prop

[Jakusters]

Dear community,
my mom has this prop in her possession for decades. It was left behind by German tenants in the ‘40s. It came with an original chronometer/borduhr. Can somebody help me to identify the plane it was made for, including the year of manufacturing. See pics for more details.

thank you,
Joep

Very nice prop and chronometer! In Bob Gardner‘s book (which unfortunately I don’t possess) is a paragraph on W?hlert props. It is rare for German props to be associated with a particular aircraft or type, but stencelling around the hub should identify the engine it was made for. This could help to zoom in on the aircraft…
