Thank you all once again. I liked nc50lc's response which explains what I suspected was happening with my original recovery seed phrase; returning zero BTC. Just to clarify a bit more. I have at least four or 5 very old electrum wallets pre-2011; all of which are displaying zero BTC on recovery and now thanks to one of you I know why. 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.

What I explained is a possibility for all Electrum wallets created pre-v0.31 or 0.34 versions
in general.
However, your situation is a bit unclear because one of your "
old wallets" can't be from 2011 since it has a native SegWit address which was only became available in v3.0 (
Nov 2017).
And just like all of us said, Electrum wasn't even released yet on the alleged creation date of your seed phrases.
