Re: Diving into an old BTC wallet from ~2014 and found a nice surprise - what next?
although one file (created in late 2015) is showing a message when I try to load it which ends: "...wallet is corrupt. Try using the wallet tool bitcoin-wallet to salvage or restoring a backup."
Generally, that doesn't end well 
PyWallet might be able to recover somethingYeah. I started looking into how to use PyWallet, but as a total Python noob who hasn't coded in any language in quite a few years, I soon became overwhelmed and discouraged. Is there a straightforward guide to using PyWallet? All the stuff I unearthed online is aimed at a much more Python-savvy audience than someone like me... I would like to invest the time in understanding it, but the nature of my life at present is that I only have an hour here and there, and very few chances to sit at the PC and really put my mind to learning Python.

The old salvagewallet option has been removed from the "core" Bitcoin Core app... so you can't use the -salvagewallet commandline argument with bitcoind or bitcoin-qt anymore... instead, it looks like there is a "bitcoin-wallet" (or "bitcoin-wallet.exe") that is now bundled with Bitcoin Core that you can use and the command is now salvage:
This is another dumb question perhaps, but how do I actually use that bitcoin-wallet command? It doesn't appear as a command line option in Bitcoin Core itself. Is there a non-GUI way I should be accessing it? I understand it's an offline tool, which I take to mean it doesn't need to sync the blockchain, but I'm clueless as to where to type those commands to interact with it. Any help appreciated.
