If you guys come to KC you can spend a day at the US National WW 1 museum and you can see an FT 17 that was knocked out on a WW 1 battlefield, then you can see an example of the 76 mm German field gun that knocked it out. Did I happen to mention they have one of the largest collections of WW 1 artillery and machine guns there. Voted one of the Top Ten museums in the country. Been there, need to go back without teenagers and spend all day there. It tells the entire story, just not the US side...well balanced, you'll love it if you come.
