1st, an image is worth a 1000 words.


On a glance, I find several Schillings in Koburg basically @ the same address: Herrngae 13

Carl Schilling

Christian Schilling

Fritz Schilling

Karl Schilling - Nachfolger: Willi Schilling

R. Schilling

Willy Schilling - Herrngae 13 - Vorgnger: Karl Schilling

I don't see a HF right off, but he could have been their father or grandfather. Since the longarm is devoid of Federal proofmarks, it was manufactured prior to 1891/1893.
