I was tearing out all the insides of the Anderson when I came to this back bedroom closet.  When I started slowly removing the panels I came upon a huge surprise!  Under the part right under the door in these photos was a number of Pennies that someone at the Anderson factory put under the wax paper but on top of the lanolium flooring then they put the wood down and screwed it to the floor. The Pennies ranged in years from 1937 to 1950 and two of them are steel Pennies from the World War 2 era when the government needed the copper for bullets and minted Pennies from Steel blanks instead of Copper!  Hope you enjoy the photographs!
