From my investigation, this is a ‘47 or ’48 Nash. I could not find this emblem among those seen of Nash’s of those years, but the grill and lights are alike to the ones of which I could locate pictures. If I am in error, I invite any corrections.
Now, from a Facebook friend of mine, I was led to this site and by looking through the photos of the various models of Nash’s shown there, I am now convinced this is a pre-WWII model as all the models made post war had park lights just inside the headlights. The photos of the ones I thought most resembled this vehicle were small and could not be enlarged, so the emblem is still a mystery.
