I thought it would be worthwhile setting up a separate newsletter where I will publish all of the articles I have written on the Seiko catalogues from the 1960's and 1970's. When originally publishing these on TGSG website, I did so broadly as I acquired the catalogues, so over there they are not in original catalogue order. On setting up this Substack, it seemed a good opportunity to re-publish these in the original order that they were published in.
