Whatever view may be held about the layout and play of Gottlieb games, their construction was good. The wider games supported the raised playfield on both sides, using an H-shaped support bar. To allow the playfield to be moved forwards, a pair of metal supports were attached, each with cut-outs to fit on the top of the cabinet edge/molding lock. With Williams games before the sliding playfield came out, in such cases I'd have to find (or even clear) a spot under the playfield to prop it up using a spraycan with the nozzle broken off, wedged into the channel of the molding lock. The underside of playfields is often extensively printed with tech information, too.
Similarly with the backbox of solid-state games, Gottlieb set up the wooden Insert Board to suit the right-handed; it hinges to the right, so access to the backbox is from the left side of the machine. The other manufacturers obliged techs to make checks in the backbox either favouring their left hand, or reaching right across. And when it is closed, the insert board drops into a locating slot, rather than simply needing a sliding latch engaged.
