Herb, those pictures and articles cover a lot of space and history!
I didn't know about Franz Ferdinand coming to India and Sri Lanka (Ceylon), nor did I know about him coming to the USA. A lot of European royalty and nobility came to the USA West, some guided by famous names. This can be found in books and in little museums scattered across the West. I will need to keep my eyes peeled for these things more closely!
His visit to Chicago: in the "colonies" over here, we call that the Columbian Exposition, because it took place on the 400th anniversary of Columbus's discovery. It went a year from 1892 to 1893. Left from that are the Museum of Science and Industry, with the simulated coal mine and the real German U505, and Soldier Field, where the Bears play (though much remodeled). There is a mansion of one of the "Copper Kings" of Montana that had its oak panels carved by German artists displayed at that exhibition, but which are now in the mansion. All sorts of things were displayed there and it was one of the very noteworthy world's fairs.
Those pictures show Franz Ferdinand a bit more trim than I'm used to seeing in pictures!
When it comes to guns like yours, the Austrian makers and others seem to be left out a bit in many conversations, though I see Ferlach guns are mentioned some in the very upscale "Safari Club" types of publications.
I am glad to see that you, Herb, one of our own, are enjoying handling this fine firearm!
(I am supposing that I don't come across Indian princes visiting the 19th Century USA West because they had plenty of their own big game to hunt!)
(PS: It's rather ironic to think that, in spite of all of the fine firearms Franz Joseph must have owned and handled, he was felled by a lowly FB Browning in 7.65 (32 Auto) from the Serbian national armory.)
