Could it be possible that password is enough to recover wallet or am I missing something?
If we are talking about the original bitcoin wallet, then no.
The wallet file contains private keys and is encrypted with a password. Without the file, the password is useless.
It seems that at that time there were no other alternatives, including the lack of a brain wallet.
Perhaps you are confusing the year, or used something very specific.
I suggest you recover hdd data, if it's worth it.
