Marvin, Welch & Farrar Vinyl LP. Vinyl’s that are very expensive and rare will be played on both sides in full. Cat No.: SRZA 8502. Would only be listed if it is a rare vinyl or slot filler. If there is a cross over between grading then it will be a mix of both, i.e. one side of the vinyl is in excellent condition and the other side of the vinyl will be in very good plus condition.
