15thc perception on swallowtail merlons?

[Pierre Dumont Himself]

Thank you, you're very kind. I want to write a longer reply, but one of the points I intended to make ran into an error: the Castle of Montmayeur with the swallowtail merlons is not the one in the Tarentaise, but the one at 45° 41′ 18.3″ N , 7° 8′ 25.2″ E. That means there is no castle with swallowtail merlons on the other side of the Alps. Both Montmayeur castles on the French side are resconstructed with straight merlons: the one in the Tarentaise Valley, and the one in the Val Gelon.
