Hause:

Me thinks it arrived on the scene around the time Poldi's Antikorro(1910) surfaced &(Acier Comprime de Wahlreyne Rust Proof -May 6th 1913 - Webley, Lebeau - Courally)

Böhler Antinit - C-0,117% Mn-0,49% Si-0.299 Ni-8,51%
Poldi Anticoro - C-0,145% Mn-0,50% Si-0,45% Ni-7,78%

I'll try to dig a bit. But I would hasten to say the bulk of the Boehler steel tubes were rolled in Liege.

Cheers,
