Brian,

The mentioned book covers a long period, so a schematic one (it contains a half-page text about the Civil War in Colombia, mentions only the P-47D's and AT-6 Texans).
I don't know, what do you need exactly but imho it would be the best if you would ask Jaime Escobar, he is the top researcher there. Drop me an e-mail, if your attempt will be usuccessful.
