Speedometer Advice Needed

[Pedr]

Here's another wartime photo from my collection.

It shows:

A ) A needle on a blank face where the fuel guage would normally have been.

B ) A painted patch over the gear speed change quadrant between 0 and 26 miles an hour.

C ) A "Ring-Grip" brand switch for the headlights.

D ) The patch covering the original idea for the position of the horn button. On the Instrument panel.
