Who put the steer head on my holster?

[kjjj65]

I need help with identification of a Luger holster as follows-
Black leather
Maker's stamp is a stylized steer(cow) head with the letter F on the left and L on the right. Location is at the inside rear of the flap.

Droop Eagle/2 stamp on the inside back of the holster.

Number 4997 stamped on the front of the holster under the flap.

No other marks.

Any information/comments will be appreciated.
