This is only one example but its all I have.
The closest I can come to a Sharon barrel of 1975 vintage is what can best be referred to as a Northwest Florida Special rifle made in the mid 1970's by a gunsmith who believed that the T/C lock and breech were just special and he made a rifle using a T/C breech/plug on a Sharon barrel. The builder wanted to verify the accuracy of muzzleloading rifles so he mounted several sights and scopes on it. The closest to the Hearts, Spades and Clubs and other identifying features was in his "Bridge" sight mount with the heart, spade, and diamond. The Club is in the shape of the architecture. I bought the rifle and added the T/C tang mounted Peep sight.
Pictures follow with the only mark being the Sharon stamp :

In my cabinet is a T/C Hawken Kit rifle (pre Warning) of the same vintage.

It has a diamond stamped near the breech and the M in a circle near the wedge dovetail.

The T/C turned out pretty good and its what started me on shooting a building muzzleloaders.
