The stock has just enough handling marks that it might be original. But after 100 years, who knows?

The Zipper barrel was nicely blued when I received it. The 38-55 barrel was the original and in rough shape. I put it in the lathe and sanded to remove light pitting and then cold blued with Brownells Oxo Blue. It took 7 applications and boiling between applications to get that color.
The receiver was worked on and case colored at CPA.
