Lucas, thank you very much for the offer. I bought the case Pete pointed me towards in the second post. It was in very good condition for a formed wood, synthetic material covered 50-60 year old item. I do wonder how long the cases were made because I also have a similar style larger case with an early SM9 wide-carriage typewriter?

I did the same with the case for my Olympia SM7.

I went with a green color that had a bit more "pop" than the original green color.

Hi George,

I patch the area with a smooth coating of Latex caulking (that contains absolutely 0% silicone).  If there is silicone, it will not take the paint, right.

As the caulking sets up for 1-2 hours or so, I use some of my spring hooks and even my dental picks to recreate the "pattern" of the original covering into the latex caulking.  Once the caulking is  completely dry, I will give it a slight sanding with 800 grit and then apply a bit of paint primer before I take spray paint cans to the case.

For other case textures, I will use pieces of dry natural sponges and use a dabbing technique.

Lots of trial & error.

Wow, that case looks fabulous
