Yes.  The claim for this patent is quite interesting too, but this is not the action I'm referring to, of course.  See how that 8 mm. vanished though!  I wonder if the sum of the friction set up between the tongue and the repetition lever and between the hardwood knuckle and the tongue as the hammer comes down would be significantly greater than in the 'standard' action and affect checking?  Probably not, and besides, the surfaces are more manageable.
