Identify the type of wooden floor - 1970s parquet

Hello. (Mods: I already posted in interior design but now thinking people here might have more knowledge on wood types. Please delete one of the threads if that’s a problem) I’d love help identifying the type of wood my floor is made from. It’s a dark reddish brown five finger / checkerboard/ basketweave parquet from the early 70s. An unfinished section under the stairs is also quite reddish. I sanded it a little with an orbital sander and the colour didn’t really change. It’s a very hard wood, can’t dent/scratch it easily. I’m including some pics of both the finished and raw wood. Thanks for your help.
