I've had a Model M Restoration Megaguide for quite a while now.
It's sort of a "one-stop-shop" for everything there is to restoring your Model Ms... for all beginners and experts alike!
It covers every step along the way, with lots of pictures to demonstrate!
If you guys have any pictures, tips, or advices you'd like to share, leave them down below! I'd be happy to give credit and add them to the megaguide!
