I fixed the cracked stock but the finish appears to be original. All I did was clean some gunk will oil and 0000 wool and it brightened right up. Most of the crack was inside and ran clear through so it impacted the finish minimumly . I had to do a minor bit of 400 grit sanding on the wrist but it blended in beautiflly. Managed to thourghly work some Gorrila wood glue after a bit of soaking in acetone. Seems solid. I have seen the proof listed as 1856-69 and 1860-69.

Thanks for all the info and hopefully a Frenchman will chime in.
