Wow, it looks like none are currently in production/on the market. Try checking your favorite secondhand sources such as Sprue Brothers, Rare Plane Detective and Ebay... I have a set from Yellowhammer that have markings for a Black Cat in the South Pacific and Lt Reid's (first PBY to find the Japanese on June 3rd)at Midway for mine that I will NOT part with...
F is for FIRE, That burns down the whole town!
U is for URANIUM... BOMBS!
N is for NO SURVIVORS...
