Or they both have a star. The Singer sewing machine has the Indian Star decal and your grandfather was awarded the 1914 Star medal also known as the Mons Star award.
I like that idea that he may have lived in India during the time of British Empire and served as an cavalry soldier. You stated what do they "got" in common. So, I'm leaning towards the machine has the Indian Star and your grandfather was awarded a metal in a star shape that may be from his serve in India.
