>>In 1881 Pieper won an award at the Paris Exposition for his innovative design. These next 2 images are from the Jury Report and based on drawings Pieper supplied to them.

Here is a Pieper side cocking cape gun based on the same design from the 1897 Sears catalog.

Do not let Monoblock, Monobloc, Demi-Block, Demibloc, etc confuse you. You are seeing translations from the French and later Italian.
Pieper was making the block then threading in the barrels. After that they were placed in a brazing oven. The modified Diana, 1891 had nothing to do with the barrels but rather the locking system. The stepped tubes disappeared and re-appeared over the years. Pieper pioneered use of brazing ovens for production in Belgium.
Early on, it was just as cheap in Belgium to produce a damascus tube as a fluid one, because of the cheap labor costs. So Pieper set up the design to be independent of the sourced barrels. He made all his own damascus in his "Brazil Works" shop.
Note in the previous post where I showed the modified Diana, the warning toward the end of the ad about painted barrels meant to imitate the Pieper monobloc. So even the Belgians had their problems with cheap knock offs.
Many years later, Beretta took the design to heart. Here is their drawing (1957) of it:
