Yes, it is not a Winchester in the true sense that it's internal parts have changed. I know the falling block angle was changed to something like 6 degrees for a better seal at the breach. I guess I just look past the small changes like a spring to some degree. But to me there is no real difference between the functionality of the Winchester or the Browning both which are made today by the same company since neither rifle is still made to the original patent or design. As Browning states in its paperwork that comes with their product,
I guess in retrospect it really only matters to those collectors of the REAL original Winchesters that were in fact produced by Winchester from the beginning of the first models offered to the public initially.
