Thanks for the effort fellas. So I guess there were at least 3 Acier Comprime trademarks:

Acier Comprime Cap w/ Chicken Hawk head - Joseph Cap

Acier Comprime de Wahlreyne - Ferdinand Courally & Webley, Lebeau - Courally

Acier Comprime de Wahlreyne Rust Proof( probably on the order of Polid's Antikorro) May 6th 1913 - Webley, Lebeau - Courally.

Acier Leugrann & Metal Vant Horn - Webley - Lebeau - Courally 17 Rue Fond des Tawes, Liege

I guess it to be some alloy & possibly some alloy with a nickel or tin component.

I wonder who was rolling it for them? J. Novotny also had similar type steel trademarks/stamps.


J. Nowotny's Special steel
