Mr. Hallquist:
Those would have been Lochat-Habran's tubes probably of Cockerill steel and I would say almost zero chance of a relationship between Krupp & Lochat-Habran, but the possiblity still exist. There were bins of barrels and one was pulled from the lot and if a client wanted Krupp tubes then they stamped Krupp on the tube, whatever kind of tube. Krupp steel may have been imported into the U.S. of A. in block form of the process was overseen here by a Krupp official. However I am open to any info to the contrary.
Kind Regards,
Raimey
