1895 Flatside Investigation|Winchester Sights|Forum|Winchester Collector

Good morning all,

Some may have noticed in another thread, I have been investigating the origins/discrepancies noted on a 1895 Flatside that I recently acquired. 

I want to make clear that this little investigation is not one of malice, I feel privileged to own this rifle and it has been a blast learning about it through my research!  I havent been duped or cheated, I just really enjoy putting together the story of this rifle!  My investigation has lead me to the sights, looking for additional insights!

I do not believe the sights on this rifle are original sights, and I am hoping the expertise and experience of this forum will assist me in making that determination, or correct me if I am wrong. 

The front sight is a barrel wrapped, ramp sight with cover.  Under a fine light you can make out “Pacific”, which I may be incorrectly assuming is the “Pacific Gunsight Company”, which opened in the early 1920’s making this an impossible original on a 1895 manufactured in 1896.  I have no other information on this sight:

The rear sight is a Marbles sight, which I understand Winchester MAY have put on some 1895s as a custom order option, but the patent date stamped on this bad boy appears to be in 1903 and 1905? Its hard to make out the stamp so I could be incorrect:

Any feedback or information would be much appreciated!
