1980's Krico catalog/folder which measures 8-1/4" x 8" with 6 fold-out pages CONTENT: The featured guns are the Model 600 in 7 variations and the Model 700 in 9 variations.The guns are pictured with short descriptions and specs.The back cover is a chart listing the models and the calibers available.There is no date or code and the 1980's is my best guess. Excellent condition
