Thanks again nc50lc. I raised an issue
https://github.com/spesmilo/electrum/issues/7893. The responses have been very interesting although somewhat disheartening. They're saying that prior to version 2.0 Electrum used a fixed word list; and if my word list is not in that list it could not have been generated by Electrum; so basically I must have used a different wallet to Electrum.
It's pretty much everything we said in the first page: the dates in your memory are off.
The issue is you're using 0.3 while the version that doesn't have a word list was the initial release up to a couple of commits.
Version 0.3 is way past the version when a fixed word list is introduced so your unique seed phrase wont work there.
A fixed word list was only introduced in this commit:
https://github.com/spesmilo/electrum/commit/93c27a62d47d9aab6b5502999df2ff184482e1e0 [2]Prior to that, Electrum will ask for a 20-word-minimum "
seed phrase" or "
passphrase" (
check my screenshot above testing the first commit)
So, you should only be trying the versions before to that commit, only the last page of the commit history
[1] (
excluding "use random seed; do not trust the user for entropy" and earlier).

Well, I know the date of purchase 100% during 2011 or before 2011.
I know 100% I used a wallet that generated the 12 word seed which I wrote down and found in my note books.
I know 100% when I plug those seeds into Electrum they're accepted by Electrum without issue; but wallets display zero balance.
I know 100% I successfully transferred coins between the wallets over a very short period of a week or 2 max and then never touched the wallet or Bitcoin again until 2016 or so. By then my PC were long broken and got rid off.
Well, memory isn't all reliable IMO.
It could add or remove details based from what you've read, heard or saw.
