I bought this bell from a railfan who lives up in Illinois, who had gotten it from the Union Pacific. The bell is a 2nd Generation WCH electronic bell, and on the inside of the bell's top, it has the date January 5th, 2011 written on it, which is probably when this bell was made.
Here it is inside the box it arrived in:
