That line and star is.....wait for it....yup, you guessed it Starline Brass.
Sorry, had to poke a little fun. There are Tons of calls about that exact issue. "what kind of brass is this with the star and line?" (me) "Starline" (them) "Oh! okay, just wondering"
Needless to say if you have not heard of them you likely didn't know or care anyhow.
