Cold blueing has a distinctive smell. Hard to explain, but kinda vinegary smelling. Fresh cold blue jobs are easy to detect by sniffing, The older the re-blue, the less strong the smell is.
Generally, cold blue is easy to spot if you know what to look for. Seeing many examples of it are the best way to learn. John Seneca Arms Co |
