Antique Carl Eickhorn Sword

My mother and father passed away and we found this among may other antiques and we are just trying to figure out if it is worth keeping put up for grandkids or if we should just sell it. We have been told that it is a Carl Eickhorn pre 1935. However we have not been able to find anything about this sword. it has etching on the blade and the makers mark on it of two squirrels back to back. The blade is 33 inches long and end to end it is 38 inches long. We have found similar ones but none like this.
