Those Mysterious Forty-fives

Norm - My spelling error. Gortz and Sturgess in their three volume reference work refer to the mark struck across the underside of the assembled barrel and receiver as a "fiducial mark". Maybe "index mark" is a more commonly used term?

Postino - Checking the chart, you are right. The M1906 case is 0.56 mm longer than the .45 ACP case. I was, again quoting Gortz and Sturgess (Vol. 3, p. 459) who reported the difference as 1 mm.
