An early-morning fire did an estimated $2,275,000 damage to a Placentia building that was once one of the busiest citrus packing houses in Orange County. Orange County Fire Department Capt. Lou Furst said the blaze at the old Bradford Bros. Packing House was fought by more than 100 county firefighters, as well as by units from Anaheim, Garden Grove, Fullerton and Orange. No one was hurt, but the three-hour blaze did significant damage to a building where the output at one time was 350,000 crates of fruit a year. The packing house, once home of the Old Placentia Mutual Orange Growers Assn., was closed in 1978. Since then a variety of small manufacturing businesses have occupied the building, which had been given status as a historic landmark.
