I would appreciate any help to identify a document found among my deceased Grandfather's personal items. I have been able to translate sections of the document but not enough to tell me what it is.

This document has the signature of my Great Grandfather, Anton Scheiba but has the birthdate of my Grandfather, Frederick William Scheiba, 29 February 1920.

Very little was allowed to be discussed about my Grandpa's life in Germany. I would greatly appreciate any help you can provide.
