MR T, my 1937 Fiat Topolino EuroRod, got a bit more attention during the last week. Above is the custom heater/defroster control panel that I built. The car is very small so I've attempted to make every part in the car do two or more jobs. This panel is no exception. The knob on the left controls heater fan speeds, the slides just to the right
control heat, vent and defrost on the heater "box" itself. The center orange lamp indicates when the secondary direction signal semaphores pop out and flash. The red lamp just below lights up when the emergency brake is "on". The two slides on the right control the outer air inlet door on the side of the cowl ahead of the right door, and the 3 position switch on the right controls the semaphore flashers on each side of the car.
This shows the INSIDE of the panel and all the gubbins that go into, or onto, it. The flasher units [top right] are for 1] the regular direction signals, and 2] the semaphore flashers. The latter are just for fun, but they were standard equipment in 1937.
This is the inside with all the bits mounted up. Two relays are mounted outside the box [extreme left side].The unit under the box on the left is the intermittent windshield wiper switch [a standard item on '70's-'80's Fiats], and the two flasher units are under the box on the right. It will get a lot more interesting when all the wires are added, plus the five operating cables. Like I said, I like to make one item do a lot of jobs, and this is typical of the whole car.
For some reason the front surface looks grainy in this photo. It isn't--it's smooth. The box is 10.5" wide and 2.75" high. My wife says I'm having WAY too much fun with this little car. I just look at her and grin and say, "Yeah--ain't it great?"
