What an amazing difference!!! The records about manufacturing the white machines were lost. I did find this for you though:
- White/Green & Beige/Tan machines were produced at Clydebank, Scotland and St. John’s, Newfoundland, Canada (Beige/Tan) from 1945 to 1963. (JB 1945-1948 JC 1948-1959 JD 1959-1963)
