I have at least four or 5 very old electrum wallets pre-2011
As explained: that's not possible.
One of those wallets is the one with the 10.7mBTC as I've been corrected to say and for which I shared one of the transactions and one of addresses in my last post.
That's also not an old wallet, the transaction happened in 2021.
Am I 100% sure that the wallet belongs to me? Yes definitely
If you're sure about that: forget about Electrum, and try to remember what you actually used. Electrum didn't exist, so it must have been something else. Have you ever used brainwallets?
you could try and recover the coins in this old electrum wallet given by this old seed. (weave circle round thrice close your eyes holy dread honey hath jan)
That's not a seed phrase, it's not even random. It comes from a poem by Kubla Khan:
Weave a circle round him thrice,
And close your eyes with holy dread
For he on honey-dew hath fed,
Only "jan" is missing from the poem.
