Some books you may want to get your hands that provides good pics of Parr's aircraft.
The best is "Mig Alley, Air to Air Combat Over Korea", by Larry Davis. It's a Squadron/Signal Publication.
i) On Page 48 is a very clear colour profile of #51-12959, the one you have.
ii) On Page 54 is an excellent photo of Parr standing by a seated Vice President Nixon (in his F-86).
iii) On Page 64 is a detailed mission description by Parr of one of his first in a F-86, the date being 7 June, 1953.
iv) On Page 68 is another great mission description by Parr, this one covering 27 July, 1953. This is the one where he scored his last victory, and also the last of kill of the War.
v) On Page 75 is a very clear photo of Parr standing with Moore, Garrison, Johnson and Jabara.
Also on that page is a picture of Parr's F-86 #24511 at the 4th FIW Team at the 1953 FEAF Gunnery Meet.
vi) Finally on the back page (#80) is a card photo set showing the 39 USAF aces of the Korean War - Parr being eighth on the list.
If you can get him that book, I'm sure he would really appreciate it. Many great photo's (quality is excellent) contained in it. Would bring back a LOT of memories of men he knew.
The other two books are not as detailed, but worth a look. One is the Osprey "Korean War Aces" by Robert Dorr and Jon Lake. Has a nice profile of Parr's F-86 #24778. In total he flew three F-86's in the War - 778, 955 and 959.
The last book is "Combat Legend F-86 Sabre" by Martin W. Bowman. On Page 30 it has a beautifully clear photo of Parr's #778 in flight, with pilots face clearly visible.
Just for the photo's those last two books are worthwhile.
Hope this helps. And I hope you enjoy your meeting with him.
