Walter Bosse? Black Gold Line BEAR Bronze Figurine 1950s RARE Austria with lots of patina

After a lot of research, I am pretty sure this is a Walter Bosse figurine from his Black Gold line. But, I am not an expert in this field. Please review the pictures for yourself, and ask if you have any questions.

I purchased 4 of these from an estate sale (where everything was from the 1950’s and early 1960’s). I am selling them separately (rooster, bear / koala bear, bird and duck). Message me if you would like to purchase more than one and I can offer combined shipping.
