Whether it's the first KR or not, I like the listing-short, sweet and it includes the important information and pics. that are usually missing (at least in most of the recent listings on bat) and then never provided until the auction goes belly up i.e., the '69 black jade vert. that has, imho become cursed as a result of a poor listing.  Inspection still recommended but this gives a potential buyer a very nice starting point to what appears to be a legit car.

It is the first KR. There are no lower Shelby serial numbers for a GT500 KR.
