As bitcoin price hit new low it is getting hard to justify selling bitcoin to pay for GPU rentals - so I'm trying to think outside of the box for finding public key for damaged WIF backup (see post#https://bitcointalk.org/index.php?topic=5380095) that happened approx. an year ago -

but Since the address in question (P2PKH) contains newly generated block rewards from solo hashing over a good period of time, but none of which were spent (unfortunately, and neither do I have an signed message for this P2PKH address) - is there any reason why scriptSig from generation transaction recorded on main net not providing me my public key?  maybe the offset I'm copying is incorrect - or it is just impossible all together

The other place I think May be of help is digging thru stratum blocks logs on the server - which had been sit dormant for about an decade in storage - but this opens up whole range of new issues (log analysis, damage to hardware not used for long time, etc)
