Helicopter pics wanted

Does anyone have any good pics of the following helicopters

Airfox-the twin seat attack helicopter based on the Alouette III
ACH-47 Chinook-the utterly ridiculous gunship
AH-56A Cheyenne

Pictures of these helicopters are rare and what I can find is of poor quality despite their interesting qualities.

I wish to now mention that with this post Is just saw that I attained Senior member status!!! I’d like to thank……
