Wanted: Len Morgan Books

I would like to buy 2 of Len Morgan's books, P-51 MUSTANG, and THE AT-6, HARVARD.
I'm looking for the paperback ones about 8 by 10 or so, don't have to be new,just in good shape.
If you have not read them, these are good sources and interestingly written.
Thanks, Bill G.

Bill,
I know I have the AT-6, I'll check for the P-51. I have many others in the series like B-58, 707, P-40 and others. Try me at airwolf1980@yahoo.com.
