Описание к видео Banknote and Coin Engraving-.wmv

A simple over-view of some of the clever machinery designed to compliment traditional hand craftsmanship and to out-wit counterfeiters. Thanks must go to those who strive to preserve these inventions and the associated history. Thanks also to the Society of Ornamental Turners. www.ornamentalturners.org www.stuartking.co.uk
