As far as I can tell from limited published s/n, mine is a relatively high numbered gun. The receiver table also carries three Patent dates: January 1879, November 1877 and January 1878. It seems to have the mechanical features described in the 1877 Patent.
As I describe in my original note, the extractor is missing, however, with a flexible rod, I can successfully disengage the slide with it's stud, permitting the barrels to swing out to the position where I believe they should disengage.
However, they do not. So my question remains, why not?
