Hi Chris,
It's difficult to tell for sure in the pictures but it does indeed appear to be a reproduction deluxe steering wheel. There are a few different ways to distinguish an original deluxe steering wheel from a reproduction.
#1 - A lot of reproduction wheels only have 17 simulated rivets (the shiny dimples) on the wheel (the original wheel had 18). - see attached photo of an original wheel - original deluxe wheel.JPG
#2 - Most reproductions do a terrible job on the "brushed aluminum" look of the 3 spokes. The factory wheels have a very satiny look and a very subtle "brushed" look to the them. The brush marks on a reproduction wheel's spokes are very pronounced. In the pictures you provided the brushed spokes appear to be have the very pronounced brush marks. - see attached photo repro deluxe wheel.JPG
#3 - A lot of the older reproductions were more grey than brown in color (especially the "base color" that they put the brown over).
Finally most original wheels are cracked just due to age at this point in their lives unless they had never been installed in a car but even then I've seen evidence of cracking. The plastic just seems to shrink a bit and crack.
Outside of tracking down an original wheel and having it restored (even then it doesn't really look right) NDP has probably the best reproduction wheel for sale. Do not buy the version of the deluxe steering wheel that comes as a kit as it's not the same steering wheel or manufacturer and the overall quality is much worse. You need to buy the standalone wheel - it's pretty much indistinguishable from an original deluxe steering wheel. Mustang Monthly did a nice article on it as well in the February 2011 edition.
