As Otto mentioned, the Uberti internals are a hybrid. The Meacham is also not per the originals; it is similar to the coil spring internals. I believe the Ballards are close replicas of the early flat spring models. I don't know about the C. Sharps, but the guys at the ASSRA most certainly will.

By the way, none of the original Winchester 1885's--except perhaps for the very first ones made--use "original John M. Browning style internals." Winchester engineers modified the design purchased from JMB, to make it easier to mass produce. I recall only a few hundred were made by JMB.
