Staunch Republican R. Jerry Parker Jr., whose Virginia-based Chesapeake Capital Corp. manages more than $1.5 billion, is the new owner of Gisele Bundchen‘s Barrow Street townhouse. Parker paid $12.95 million for the house — $1 million less than its asking price, reports The Post’s Jennifer Gould Keil. Parker got his start in the secretive “Turtle Program” of 1983, when trader Richard Dennis sought to prove that great trading was a skill that could be taught. Dennis, just back from Asia, boasted, “We are going to grow traders just like they grow turtles in Singapore.”
