You make a good point about why so few Jaegers made it to America -- the people who owned them had little reason to leave Europe and the people who wanted to come to America didn't own may guns.
It reminds me of a great book I discovered over Christmas that explains how Europeans evolved as hunters, but then in fuedal societies were punished, tortured, or even killed for hunting. See: Journey to the Ice Age: Mammoths and Other Animals of ...Dutch illustrator Rien Poortvliet. Lots of illustrations by a guy who loved sitting quietly in the woods.
The traditional European foresters/game wardens were not wealthy, but were were armed with rifles. I wonder if there was any such thing as a common man's Jaeger, or a common man's English sporting rifle?
Anybody seen a poor-boy Jaeger?
