I grew up during the time period but was still in high school by the Time Bush left office having pardoned everyone. I am interested what we have been able to discover since the investigations have finished.
Hi, check these out
author /u/Malcolm_Byrne discusses the affair in AMA: Ronald Reagan and the Iran-Contra Affair
/u/Demeche gives an overview and cites sources in Iran purchased about 2,500 TOW missiles and 18 Hawk missiles during the Iran-Contra affair. What did Iran do with all those missiles?
for a pile o' sources, see /u/tjcase10 's answer in What exactly happened with the Iran Contra affair?
I hope this is acceptable as a top level comment, but here is a link to the downloadable version of the congressional committee's investigation. It's the source material for most books about the Iran-Contra scandal so it's worth reading in its entirety if it's something you're very interested in.
