The numbers on the leaves, for the MB locks, are on one side right next to the little tabs that stick out. I didn't notice them until I really started to get the leaves clean.

I have done too much rust removal from things like cast iron machine tables and many other parts. I have found that for flat surfaces and even round ones a single edge razor blade will actually scrape off the rust without distorting the surface like sandpaper or a stone can. Lube the surface up with just about any oil then use the razor blade to scrape the rust off. If it is really bad I will coat with Marvel Mystery and leave for a couple of days so it will soften up. Once I start scraping, I just use mineral spirits. Also, IMHO scraping takes less time than sandpaper if there is a buildup of rust on a part.
Thanks for the post. My wifes 1985TD hatch lock would not accept the key. I was amazed how much crud was in there. Gave it a good cleaning and lubed with marine grease and it works like a charm now.
