ChiefShotguns,
If I may ask about your Masquelier Daly O/U? ...the one with a left/right toggle in front of the trigger (barrel selector)..Is the gun marked Daly, Masquelier, or both? Are there any Masquelier touchmarks like the triange mask? Maybe a raised D in a sunken diamond?

Are there any indications whether or not the action was supplied by Suhler Waffenwerk (Merkel)? Not necessarily German marks, as Suhler Waffenwerk had a facility in Anvers Belgium (now Antwerp)...any GM marks?
