Photos are dark, as stated, but in focus. No rolling, falling, dropping, swinging blocks in evidence but it's a Charlin slider, Charlin between the ears of the toggle, bit of engraving of pinwheels in negative space circles surrounded by other pinwheels or stylized suns with flames, or something and a few leaves on the fences.
Mike, the gun in the photos has two triggers. Didn't surprise me on a Charln but did surprise me after reading your description and exprecting only one.
You'll still want to go looking for absurd levels of French proof (the multiple palms) on the barrel flats. To disengage barrels, open the breech by sliding breech block to rear, depress the round-head button on the bottom (I can't even remember precisely where it is, bit aft of what passes for a forend on these I think). While depressing button, slide barrels to rear and lift out. The "forend" will stay with action. Reverse to reassemble except that you won't need to operate the pushbutton to release a latch.
