DB,
Were there any other patent dates? An "Oct. 15, 1926" date was added and since the Army Special wasn't renamed the O.P. until '28, it seems likely it should have the later patent date. (Unless it's a *really* early example. Does this gun happen to have a SN in the 54x,xxx range?)
I believe the barrel patent markings were retained 'til a couple of years after the war. The WWII Commando versions of the O.P. were usually found so marked.
