Convertible pax/freight DC-6A delivered new to Flying Tigers in March 1954. Operating a transatlantic charter to Manchester. Sold in May 1958.

This airplane went on to fly with Zantop and more recently Conifair in Canada.

At the time of this photo, Northern Air Cargo's once very impressive DC-6 fleet was slowly being phased out by NAC's new owners, and was already down to five flyable aircraft. Only four of them saw fairly frequent use, one of which was this N6174C (ex C-GBYN, N1281, N402US, N34959). It was acquired by them in June 2002, and eventually withdrawn from use in Sep 2008. A little over a year later this oldie was bought by Everts Air Cargo, and was still in use with them by 2016.
