OK, so its an old paint job, not quite good enough to be factory and too good to be an operator, so how about a jobber, one of the companies who ran the ads in the old Billboard magazines offering used games for sale?

Some of them were pretty substantial operations, and they would have had the facilities to "detail" a game for resale (or for export as in the case of the game above with the coin entry for French Francs). They also wouldn't have been real picky about how they repainted a cabinet as long as it looked good.

In fact, a lot of them were in Chicago, so it's not completely far-fetched to think of them hauling a truck full of used cabinets back to Gottlieb and having the factory hit them with a fresh coat of paint, especially since most of the used game dealers were also selling new, and what they took in on trade helped sell new games. In that case, Gottlieb would probably have used whatever colors were already mixed and whatever stencil was handy.
