From Puraye. Note the giant grinding wheels in the background
Some time between 1897 & 1907 the Henri Pieper conglomerate exchanged their 2.4m grinding wheels for either Pratt & Whitney or Loewe grinders. Peter may have a more accurate date. Pratt & Whitney seemed to have better enroads to the Belgian makers but Loewe did have presence as did the F.E. Reed Company regarding gun barrel lathes, France's Barriquand & Marre miller as well as other American makes. I'd say most of this effort was more than likely on fluid steel tubes and what we may find is that the tubes on pre-WWI American offerings were made on Pratt & Whitney machines in Liege.
