The British and Belgium gun makers had liquid nitrogen back in the 1880's--- 1900???
No. But who said they were making damascus 1911 slides in the 1880s? Who said anything about the british or belgium other than you?
If he were talking about a pistol from 1911 i would be like "no dont do it... for the love of antique firearms stop". But if you are talking about a 1911 .45 slide.
