After taking into consideration another poster's input, I came up with a more accurate estimate for Mandingo. The doll is 213, maybe 214 pixels, and his dick can be anywhere from 175-180 depending on what you consider the NBP starting point. I settled on 178 and 213, putting young Mandingo at the lower end of the 9.5-9.75" range that I originally came up with.

This is the closest match I could find, although Mandingo is at a much more flattering angle, along with a wide-angle lens, and TD is still not fully hard (although this is the hardest I've seen him).
I lined them up as best as I could, I tried to remain as objective as possible so as not to make one bigger than the other. Once I aligned them, TD's dick was visibly 6% longer than Mandingo, despite the camera angles in Mandingo's favor.
On top of that, Quinn Wilde, the woman with Mandingo, is 5'3". Gia Regency is 5'6". About 5% taller.
Here's how all of that works out:
