It looks like a 1955 1st series truck. The identifying characteristics are:
- white grill
- hood side emblems

You are right about the holes for the rectangular parking lamps looking odd (this may be due to the angle of the photo). Maybe someone knows if this has something to do with this being a big truck and the smaller-truck parking lamps are a different size (Spanky would know, I bet)?
