What about the two different Registrars listed? E.F. Lavender and Mr. Miller??
One is the “Registrar” and the other is the “District Registrar” ?? Two different positions?
I don't think it's Mr. Miller, but rather M.R. Miller. If the typist had left out the period after the "M" then typed the "R", he/she would have had to manually push back and hold the carriage and then overstrike part of the "M" with a period which is pretty much what the image shows.
