This is a 1958 Musical Tippee-Tim The Dancing Monkey Tin Crank Handle Musical Box with original red strap!
It has a crank handle on the side to play the music. It plays a full song, but I don't know the name of the song. It also has a red plastic strap so it can be worn like an organ grinder did! The box is tin and measures approx 8x10 inches and 4 inches deep.
