Bruce, I might just use photoshop Blansky, I will print with more contrast and bring out the sky. I tend to do pretty much straight scans as I'm crap with photoshop!
I saw an old Buick on the cover of a magazine with the front emblem facing in the wrong direction as well as the steering wheel on the opposite side once. Took me a second to understand what had happened with the neg / pos flop.....btw: Enjoyed this photo, Tony. Old relics found in fields seem to have a certain character about them. This one seems to also.......
