This still has the original 28" target weight barrel. These are lighter than the C barrel I believe.

I did some internet research and the M52 has a
Wikipedia page. I know these are only as good as the last contributor but this looks well done and they state the standard target barrel is 28" and .75 at the muzzle. Mine is 28" and .71 at the muzzle, definitely a target barrel and a 52C.
Just pulling it out now after several years I had forgotten I had George Beitzinger D&T it for Warne Mounts. I think I'm going to see how well the old barrel shoots before committing to stock work.
