Hi 'Nando,

Very nice sample, that one!

I would date it to the 1760's-70, so strictly speaking it does not really belong to the real Queen Anne group any longer, which usually comprises the late 1600's thru the early 1700's. Moreover, the Queen Anne butts are significantly rounded in a bulbous shape.
I realize, of course, that common language use summarizes much later types among the Q.A. type, even at auction houses.

For a better understanding, I attach images of a 'real' Queen Anne pistol of ca. 1710-20; I just googled them.
And a colored engraving of the Queen of ca. 1706-10.

Best,
Michl
