Old 1920-1930 "Gaucho" Knife - Any Info Would Be Greatly appreciated.

Boaught a old Boker Arbolito knife for $100.00 yesterday, I don't know much about these, couldn't find a lot on the internet but I knew this would be a great place to ask about it..
It has.800 ( silver ) marked on most or all of the metal parts of the knife and sheath ( not counting the blade itself ).
It has H Boker & Co. and then has the Boker Tree emblem and then under that it says ARBOLITO, then closer to the handle it says Alemania ( which I think means Germay ) .
The top ridge part of the knife says ARBOLI
It's a pretty knife, highly oramented and I didn't have one so I bought it.

Going by the stamping on the blade I think the knife dates 1920-1930 but I'm not sure..
