The rifle was made as a centennial celebration limited issue in the mid 70's.
They had two models, one trimmed in brass and the other in browned steel.
I don't think they ever called it a Hawken,, it's always been a Mountain Rifle.
At first people felt it was just a knock off that was simply a mix of assorted parts and wouldn't amount to anything. Very shortly they where found to have tack driving accuracy and surprisingly reliable.
Because of the limited issue, the Rilfes today command high prices, lowest I've seen was $600 and as high as $1600 for mint in the box with papers,
