Yes, would the OP provide several more photographs in better natural lighting, that would be greatly appreciated. It's difficult to tell from the photographs provided if a refinish or not.
It does look awfully shiny, but the serial number looks very crisp and the cam lock does not look to be refinished, both of which suggest original finish. Oftentimes, a refinished Triple Lock revolver ends up with a refinished cam lock, reblued or renickeled, whatever the case may be, obliterating the original case coloured surface.
Do you have a factory letter? If not, here's what it will say:
Triple Lock, sn 9383, 44 Special, 6 1/2" barrel, nickel finish, gold medallion grips, shipped to Cowdery Export Co., New York City on October 6, 1914.
