Antique cast iron toy Cowboy gun pistol 3.5"

This is the cutest little toy cast iron gun, Marked Made in USA on one side and COWBOY on the other side. The trigger still works and gun is made in 2 pieces plus the trigger mechanism. THE RUST IS SMOOTH, NO ROUGH. The light rust is very smooth and it measures approx 3 1/2" long. It has been kept in a cigar box for many many years, Very nice.
