Early 1900s sideboard

Hello...trying to identify a sideboard that was let to me. I also have buffet and table but this sideboard does not seem to match the fit as being the same. Im sure its is from early 1900s but too San victorian or jacobean I would like to know. Cant find any tabs or labels left on furniture. Well crafted and sturdy oak is what i was told. I think mahogany though. Thanks for your help.

Good
