Where can I download the Nokia Series 40 Application Development SDK?

Question

Nokia

Hello. I actually need the Series 40 SDK, only here is the Series 40 2nd edition . I searched for a long time, deeply, but did not find it.
There is no Nokia website, only version 5 and 6. All other links on the Internet lead to the former Nokia forums, which no longer exist, and the download links, again, are invalid. I would be grateful for help in the search. Thanks in advance.
