I am fairly confident that the encircled AC is that of Aimé Coquilhat (1854-1880 - dates registered with the Liège prof facility???) @ 1 rue des Augustins in Liège.

I do hope Dr. Hause pops in to give an ID of the pattern welded tubes.

Too there are some crown experts here too that might put a title with the Gold Crown.
