500Nitro,
I can see the smooth rifling allright. By mint, I meant that there is no visible frosting or corrosion. However, it is a lot harder to assess the wear, as there is no sharp edge rounding that you can base your assessment on.
The gun is approx. from 1899 (SN 08456) so it is likely to use the 215grs bullet.
I don't see any evidence of reregulation.
On another subject I have been trying to get a hold of David Perkins who is supposed to have the CL records, but to no avail. Has anybody been successful in contacting him?
Thanks a lot,
WC
