Thanks to Sarah Staples for giving eWillys jeep experts a nod in her newest article. We helped her identify this wagon as a 1961 Traveller. She told me that the rarity of the vehicle helped her sell the travel piece to her editor. She wrote it for "Postmedia Driving, the driving section of newspapers across Canada."
