1877 Achte Bezirk Brigade aus Schlochau

I have a copy of a military service record from 1877.

The script and the terminology have changed.

I believe it is a "loosungs Schein", a discharge paper, which

released my great-grandfather from military service due to a

"great scar on the foot".

He was given an "Ersatz Kommission"

Is someone familiar with this?
