Looks like you're well on your way, Phil.
Now that your pointed it out, I had never noticed the missing passenger seat on the Revs car. It also lacks the ventilated driver's seat that is so typical of GT40s.
This car was given to Ford of France and ran several races after Le Mans. Most likely the second seat wasn't required at those venues and the French drivers preferred a different type seat. The car itself was acquired in a very original condition and has had minimal restoration.
By the way, you didn't miss anything on the Revs site, the garage shot was my own. I do have more detail photos, let me know if you need any particular view and I'll check my files.
Keep up the good work!
