Looks like an old 50s 60s j c Whitney grille. They sold for about 10 bucks. Had one at one time for a 51. It was made out of 4 pieces of steel bent and welded together.
I reckon it's home made/ custom too too. I think I have a photo of this car with the stock grille, this is heaps cleaner looking.
So busy looking at the grille, I never noticed that car is right hand drive. Now I'm wondering if that opens a whole new discusion of what the grille could be.
Aunt Sophie's 54; This was my wife's Aunt and Uncle's 54 Ford Customline : I find it interesting, based on the dates on the license plates, that they held on to it for quite a few years.
