looks like N6329T when owned by L. and J. Cullum.
This is a P-51D-25-NA, s/n 44-72777, c/n 122-39236, ex TNI-AU: F344. Purchased from the Indonesian Air Force in the late '70s by Steve Johnson, disassembled, and sold as "kits". This one was purchased by Al Letcher and restored as "Singapore Sally" , registered N8064V. Now owned by Steve Seghetti as N151D
This once belonged to Jay Cullom from Texas. Great Video available of him flying the airplane including a Spin sequence. Now with Joe Thibedeau

Easy one, its the world's fastest Skyraider pilot Jay Cullum's P-51
This looks to be the one that was owned by Jay Cullum (spell?). If I recall he and his dad owned it together. I have pictures of this one at a CAF airshow held in Denton Texas back in the late 80's. It changed owners shortly after I saw it and Jay went on to own his Skyraider and T-34.
