What Robust Redhorse said. They see those animals everyday and if there is a problem with say the cape, they usually have an extra one around. Not to many Kudu capes around Macon... And the price is right, you just have to go to the airport and pick up a crate full of goodies!
There is a "dip & pack" process by which the skulls are boiled, and bleached. The capes are de-fleshed, and then dipped in a chemical bath of formic acid and sodium carbonate that eliminates any bacteria. Then they are re-salted and treated with a powered insecticide. The trophy parts must pass through his process to meet the importation criteria of US Customs & USFWS. This process takes anywhere from 90-120 days to complete with any of the better African facilities.
