When I was into restoring antique American cars, I know of a car that had very limited production and the carburetor was missing and none available! They took a model from another car, made a mold and cast a new one out of brass! I don't remember the cost, but it was very high. I also don't remember the make for sure, but I think it was a Durant. I don't think it's spelled right, but you get the picture. To this day, there are many cars out there that no parts are available for, they have to be made. So were very lucky to have had people like Al Moss around, who was a key player in getting parts re-made for our British cars. He knew the NOS stuff would run out eventually and we would be left with no new parts. Didn't know him personally,(sad to say), but knew of his many achievements. Thanks Al, may you rest in peace! PJ
