Help to ID, Boker knife with two tree marks

[Kat_H]

I have these knives. I was told could be Boker, an old mark, but trying to find anything on them or the double tree mark & why was used.
Blade is about 9 3/4" long, handle I believe is bone, carved as a horse.
I was trying to locate anything on these marks, real or fake?
Thanks for any feedback! Kat

I do not think, that this is a genuine Boker knife. As far as I know, we never used two trees on a knife. even the style of the knife, is nothing that is made "traditionally" in Germany... it looks too exotic
