Is this a factory color? Or special order ..

So the wife is staying? Just as well, the disposal fee is outrageous. Apparently they are extremely toxic!

 

The entire Glidden Salchi code 106-M-73 / BSB 133-M-7 was used until 1978 then it becomes 633-2-007 but this is the same color.
During Glasurit period of Marrone, the code change from FER309 to FER303/00C in 1981 and FER800/00C in 1983. It is sometime called Marrone Colorado but it is a dealer name.
From 1984, Glasurit propose a color named Bruno Mogano that could be the other tint of the Marrone that mwr4440 talk earlier in the post but I have never seen a car with that color and it was not available for carbureted cars. It is more like "Chocolate" but with more milk in between Oro and Marrone.
