Mike,
I'm more familiar with the Belgian shotgun proof marks, but what I see on this gun is that it was nitro proofed between 1898 and 1924. Looks like only one set of marks to me. What makes you think it was reproofed? As Argo said, I'm sure we'll get a good answer from Dr. Drew and/or Raimey shortly.
