Vinyl or Styrene ?

[mr. splendid]

A friend just got a copy of the Heart Beats - Cryin' Inside with a rather nasty warp . Unfortunately he is not able to discern if it's a vinyl or styrene press and I don't have a copy of this one . Anybody out there who can help ?

I have both Heartbeats 45s, they are vinyl pressings
