Just to end this off, it came with a Mac Plus bucket, Mac Plus motherboard and an 800k drive with new drive mount. It also had a zip tie that ties the motherboard to the side frame which I thought was not normal. The zip tie had a label that was dated 1988 which I assume is when it was upgraded. Everything else including the analog board, front face, frame and tube look original.
I believe the earliest 128k's used a black plastic sheet behind the analog board as opposed to the white one with red lettering that's normally found in Compacts.
Yes, the "black plastic sheet" is actually a dark gray cardboard/fiber analog board protective cover. As noted, this was on the very early Mac 128ks. The white plastic sheet came later.
