Velvet Verniers
Having obtained a number of these National drives and dials I was
wondering if anyone knows of a good source of information on them. I have googled up a number of sites that mention them in passing but I would like to get more information. Some of the dials are pre WW11 and made of Bakelite whilst later ones have black aluminium dials. They all have the velvet vernier planetary reduction drive.
