Is there any where to get information on a crescent Firearm No 60 emire hamerless 12 gauge shotgun?

From the 2002 Standard Catalog of Firearms:

In 1905 Crescent's first hammerless sidelock was introduced as the American Gun Co. "Knickerbocker" Model No. 6. This very popular model became the Crescent "Peerless" No. 6 in 1922. In 1928 it became the Crescent "Empire" No. 60. and in 1931 the Crescent-Davis "New Empire" No. 88, "New Empire" No. 9, and "Empire" No. 9.
