The sample games in this listing have very different playfield artwork than the production version. The flyer shows the production version. The sample game shown here with serial number '01016 S' uses a plastic playfield overlay glued to particle board. In one image, the overlay is shown as falling a half-inch short of the edge of the board. The game owner was not sure if this half-inch margin appeared on all edges of the playfield. Tim Arnold contacted us with the following information for 'Volley', 1977 'Big Hit', and 1977 'Jacks Open': I have noticed a mystery on these three games I can solve for you. I have had many examples of these machines over the years. Playfields with PAINT over [flipper] swipe area and top arch are made of CHIPBOARD! I first saw this at Cleveland Coin back in the day when we were thinking of buying the game off the floor. Our salesman told us to take one in the box as the painted over area was "Pressed wood". I later talked to Cliff Strain [in Sales] at an annual trade show. He told me they were trying new materials because of a spike in the price of plywood. I have had two of these three machines since then, and the paint seems to stick to the wood just fine, but the surface turns rough and bumpley (sic) under the paint. We previously showed a date for this game of August 26, 1976. The new date is per Gottlieb documentation.
