... Do we have any examples of overseas registrations?
Anne - Yes, in the early '30s, on a final version rest-of-the-world (excluding US and possibly Canada) Lillicrap's Hone. In addition my first reaction to the central stop was that it is perfectly natural for a continental European mouldmaker to separate off his thousands that way - it makes the number easier to read.

Notes. I am fairly certain of my transcript and its accuracy, but would welcome any corrections or variants. I'm certain of my "NO"s and "No"s, save for the first which is rather borderline. All the stops that appear are full stops at the base.
The France and New Zealand numbers look like classes/categories, rather than actual allocated numbers. Later versions might exist with these changed to allocated numbers.
Please let me know of any variation at all, including differences in the full stop distribution.
