Thanks for clearing that up.
I did have lots of photos of the others ones too and they all seemed to be Pan Americans, which confused me somewhat.
I posted this one because a) I liked it best and b) I thought it the least recognisable as a Packard.
I'll change the heading accordingly, but I've given aaron his point already and can't change that - it confused me and it does appear all over the Web as a '51 so we'll just have to live with the slight error!
