From William Brown:

Santa Maria pressings were usually vinyl, on top of there being hand-etched "S's" of varying thickness within the dead wax (I have some copies pressed by plant which either put on "SSSSSS" or "SI," "SII," etc.); plus labels (of 3.625" diameter) pressed onto the records. (Certainly, by the time Zappa first set up business with Bizarre/Reprise, all Santa Maria-pressed 45's were vinyl, with the characteristics I just mentioned.) The other two plants - Pitman and Terre Haute - pressed in styrene, with the labels (of 3.5" diameter) glued on.
