1912Staver, I am in Argentina
Yes Spring pick up points are very unusual .
I was thinking of some rare American car or one with little production series, but I can't find anything similar. Maybe it is as you say and it is European.
Yes, the query is for the frame bottom, some chryslers had that similar type of support in the front leaf springs. but they are not the same, I cannot identify it, yes not a cheap car
