Early Colt 1911 Patent stamps

In the Clawson book it says the final patent date, August 19, 1913, was added to the Colt .45 slide after serial number 83,856.

There are two 1913 guns now listed that have the final patent date, but their serial numbers are in the 25,000 and 31,000 range.

Is the Clawson book accurate? Do both these guns have the incorrect slide?

  When inquiring about specific guns, it's usually helpful to post photos or links.

  EDIT: Colt did not stamp the SN under the firing pin stop until 710001 (on 1911A1's).
  
  EDIT 2: It's not just the patent date. The large block sans serif lettering on the right side, & the shape of the recoil spring housing, would place the slide in the late 200000's. The wrong slide is not really that important on a gun with 0% original finish.

  I don't have my book in front of me, but I would pop the firing pin keeper out and see if the serno matches. I've found one or two errors in Clawsons' book, but I would doubt he's wrong on this.

  Could Possible on a 1914 pistol but in my opinion not in a pistol shipped April 1913 "25XXX or May 1913 "31000" after serial 89,000 very likely and after 95,000 all should have later roll mark with 1913 date . It took almost a year after Pat 1913 was granted before slide Roll die was changed to reflect the 1913 date.

  Here is 25,026 showing the 1913 patent date.

  The rampant colt is in the middle of the slide, which the book says didnt happen until 1918, so I guess this is the wrong slide for this 1913 gun.

  slides may have been swapped at a maintenance depot. Checking the # under the retainer will tell the tale.
