Many of us are aware of the 2 whitepaper drafts which satoshi published prior to the now available and famous "Bitcoin: A Peer-to-Peer Electronic Cash System" document
One was the now lost bitcoin monument "ecash.pdf" which was published on August 22, 2008 and other was the "bitcoin-whitepaper" draft from October 4, 2008.
I downloaded the ecash.pdf from Draftable.com but the metadata points that the file was created on August 28, 2017 and I am not sure if this was the original version or not. I also got a PM from a bitcointalk member asking for the original pdf with 2008 metadata and my days of searches never yielded any results.
Are there any old members here who have spoken with satoshi and do have the original ecash.pdf paper? It would be really great if someone can share the original pdf and help us in knowing what was the original draft is all about.

Subject: Citation of your b-money page
I was very interested to read your b-money page. I'm getting ready to release a paper that expands on your ideas into a complete working system. Adam Back (hashcash.org) noticed the similarities and pointed me to your site.
I need to find out the year of publication of your b-money page for the citation in my paper. It'll look like: [1] W. Dai, "b-money," http://www.weidai.com/bmoney.txt, (2006?).
You can download a pre-release draft at http://www.upload.ae/file/6157/ecash-pdf.html Feel free to forward it to anyone else you think would be interested.
Title: Electronic Cash Without a Trusted Third Party
Abstract: A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without the burdens of going through a financial institution. Digital signatures offer part of the solution, but the main benefits are lost if a trusted party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as honest nodes control the most CPU power on the network, they can generate the longest chain and outpace any attackers. The network itself requires minimal structure. Messages are broadcasted on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.
