I have spoke to a guy who worked there: Here is what he wrote:
"I started working at Nankivell in '65 when I was 17 as a summer helper/apprentice. Nankivell had just opened in '63? and around '85 the name was changed to Hubler Chevrolet (Frank Hubler was Jim Nankivell's accountant and brother in law and bought the company when Jim retired) Hubler relocated to a new building at its present location about 3 miles south in Greenwood in "87. For many years I've had several "Nankivell" labeled things around my garage.(your more than welcomed to them if I can find them) I remember a cast chrome Nankivell license frame and some metal dealer emblems maybe some decals yardsticks keychains. Nankivell were one of the first dealers in that area to switch to stickers. Ill try to see what I can find. I talked to 3 people today who are going to see what they can find as well".
I was shocked when he was so willing to help a stranger. I had another guy send me these matchbooks
