Joe, from the Warbirds Resource Group "Forgotten Props" and Aviation Archaeology pages, along with a bit of my own scrounging, these are the ten P-51D's that were manufactured by NAA as TP-51D's (later re-designated as TF-51D's with the formation of the USAF in 1947) and their known assignments. Unfortunately nothing can seemingly be found on 45-11450 with internet searches, and none of these are known to survive today.

The factory-produced TP-40N low figure of 26 I wrote in a previous post is based on information from research that had been done by Jack McCloy at Fantasy of Flight during the restoration of their original factory-produced TP-40N. Of course it is going on about two decades now since then, and perhaps further research has exposed more TP-40N conversions? The factory TP-40N conversions followed two dual control P-40E conversions, sometimes referred to as the "P-40ES". Online, I've read that as many as 40, 50, or even 100 P-40N's were converted - I haven't seen the evidence of that.
The last photo in Mike Furline's post is of the TP-40M conversion, that had originally been built as a stock single-seat P-40M and was being used as a trainer in Florida. It suffered an off-field belly landing and during the repairs was modified with the TP dual cockpit conversion.
Here is a rather neat looking Russian P-40K two-seat conversion here (obviously the center plexiglass tunnel isn't nearly as long as in the factory TP-40N conversions):
http://ram-home.com/ram-old/p-40-uti.jpgAs an aside, there was also recently some discussion on FB concerning others, like the TP-39Q's and TP-47G (both which looked hideous compared to the TP-40N and TP-51D).
