Circa-1960's-70's Universal Firearms Corp. circular which measures 8-1/2" x 11" and is printed on both sides CONTENT: Both sides of this single sheet are shown.The guns are pictured with descriptions,specs and Retail Prices on the opposite side.It does list the Ferret as available in .256 and .30 calibers.There is no date or code and there is no zip code but I believe it is mid-1960's Excellent As-New condition
