Helps to recognize propeller

[german]

My name is German, I am from Argentina and by inheritance I got this propeller and I would like to know which plane it could have belonged to, thank you very much

I can't identify it, but with a diameter of 86" (check to see if that's the actual length) and Warner hub, you could look on this page for props with that diameter (i.e. an 86 prefix) using a Warner engine and narrow the likelihood down to a few airplanes, notably Fairchild, Meyers, and Luscombe models.

Unless there is a specific aircraft stamping or other documentation you can't isolate these to a single model, just a general application.
