Distinguishing Copies

In the ensuing several years, respected suppliers have followed time-analyzed requirements for layout, alloys, and fabrication. But that hasn’t prevented other companies from attempting to swoop into the market with non-standard items. There have been over 80 variations – of varying good quality – introduced in the very last five a long time. So, how can a buyer explain to the difference?
