Was digging thru some old calls and came across one of these.  Any idea on time frame they were made and are they worth a darn.  I'm sure I have the original striker for it somewhere as well.   This is what it looks like.

				I have a Cedar one that I bought in the early 90's, but not sure of the years they were made. 
			
			
			
				I have one that looks just like that. Probably bought mine 1999-2001 time frame. I still use mine, but it's the only trough call I've used, so not sure how it compares to others.
