Tom Fuller established his 'hand knapped black English gun flint' business in England back 1973, and is the only commercial company name that I'm familiar with that produces black English gun flints.
Does anyone know the name(s) of the other companies prior to 1973 (and/or now) that made/make black English gun flints?
