The 1948 Oliver 70 I grew up on had a black background white lettered ammeter in top center, top right was the heat gauge (yellow background, I believe), and the left top was the oil pressure gauge.  Lower left was the combination light switch and high/low generator charge switch.  One pull out turned on the lights and kept you on normal (low) charge.  Pull it fully out and it was on high charge.  The button was aluminum-colored and flat.  Near it was the starter engage button (push-spring). Lower right was the starter switch, as was the choke.
