GRT Record Pressing

Formerly Mid-South Record Pressing Company, under this name from 1974 until the plant closed circa 1979. GRT Record Pressing was acquired by GRT Corporation in the 1969 buyout of Chess Records.
GRT pressings may be distinguished by a "muffin"-style pressing ring area with a 1.125" inner ring; sometimes the letters "GRT" appear etched in runouts.
