I think I saw that episode... or maybe another.  The one I saw was a sporterized Krag, with an obvious 1903 front sight.  I told my wife that it was worth between $300 and $400 tops.  I about fell out of my chair when their "Expert" told them it was worth $2000+!!! 

I like the show too.  They did an entire episode with my cousin in Wisconsin (episode was about Beer and Oktoberfest, and they were picking Frank's Oktoberfest buddy - my cousin).  I remember he was showing pictures from WWII where his father (My grandfather's brother) was a surgeon.  Seeing my Great Uncle in those pictures what a bit of a thrill for me!!!
