For all intents and purposes, there are no current teachings/beliefs of JWs that are the same as in Russell's day except:
- Soul sleep
- 1914 is the End of the Gentile Times
But Russell had a completely different idea of what 1914 meant than what JWs currently believe. He believed it would be The End culminating in Armageddon, not The Beginning of the End—the meaning of which would be revised at least six times between then and now culminating in the current "Overlapping Generation" nonsense.
So essentially there is only one doctrine which Russell taught that is still currently believed by JWs and it isn't even an belief exclusive to them.
