93 vs Mark II

Hey y'all need some help here.

My understanding is that at some point, Savage changed the 93 action design so the 93's of today are not the 93's of years gone by. They also have done the same with the Mark II.

What years did these changes take place, and what were they?

Were the 93 and Mark II ever the same as one point in time?

Change took place sometime in the 2010-2011 timeframe. Details on the differences can be found here:

Of course there is an article on this, why didn't I look up the articles... Thanks J.
