Welcome. That is neat that it has the Singer mat. I have never seen one in real life.
Those are my favorite decals. The first one I saw, but was not in a position to buy it, seemed to have a lot of rose pink and green in the decals. They also seemed rather translucent. The machines that I have been able to get since then, seemed to have been washed out from what I remembered.
There are some stickies at the beginning of this vintage and antique sewing machine section of the board that have some very good instructions about how to clean & use this old machines. The two I'm referring to are rather long, but have a lot of good information. The second one is how to re-shellac the machines. I know that Glenn still checks in here and has been about answering questions. I know several have good outcomes following his instructions.

Glenn also did a couple of threads about the cabinets. Those are:
Cleaning and Reviving furniture(Sewing cabinets)
refinishing sewing machine cabinets
That is a good machine to sew with.
