Short dress bayonet (two makers marks?) - From lot just bought

Hi guys. Im confused by this one. Are there two makers marks here?

The kings head and the knights head are the symbols of the two companies that became Weyersburg (King) Kirschbaum (Knight) & Cie. They later rebranded themselves as "WKC" and lost the Kings head. So the two logo double heads may have begun being used in 1883 when the companies amalgamated, or some time after that. Certainly by about 1900 they were using both and this continued up until the First World War.
So what we can say about this parade bayonet is that it is imperial era and possible pre WW1. I might add that the blade is of a style called a Carbine blade and is also used in the so called Luftwaffe Forestry knife.

Thank you Anderson. Very good info. I was scared for a second that it was a fake because I had never seen this before on a WWII bayonet.
