The record contains a double sided internal layer for a printed circuit board. The printing is done in copper. The copper forms a lattice pattered boarder, of varying width, around all four sides of the layer. There is also a boarder of punched holes around all four edges. Inside the lattice boarder is a copper rectangle with a matrix pattern. Along one side's long edge there is printing that reads "VEE MCDATAMB PWB 901756-/A/ ASSY 901757 LAYER REVISION A." The reverse side has printing along the long edge that reads "VEE MCDATAMB PWB 901756-/A/ ASSY 901757 LAYER REVISION B."
