It seems like it should have "A Kennedy" in the back seat for sure! MM
Methinks more like Milburn Drysdale. I think I saw more than one of these on the "Beverly Hillbillies" over the years!
You are quite right, Kurt:Milburne was driven in factory-built Imperial LeBarons.
I had a 1964 that looked identical to the one in the photo other than the wheel covers (and grill which is not visible) as twenty were started for 1964 but ten were modified very slightly and sold as 1965 models. I bought it in the early '70s when it was still fairly new and owned it for many decades but no longer own it. I never did find out who owned it originally but I was told when I bought it that it was being sold on consignment for Tom Mix although I never was able to confirm it.
