1955
For some unknown reason the “Club” date stamp was not used in 1955 and only the ordinary mobile date stamp was used. That year mobile office number 3 was again stationed at the Ground but the mobile date stamp used here reads MOBILE POST OFFICE No 2 A but note that the 2 is upside down to normal. It is likely that when this stamp was being brought into use the figure 2 was inserted instead of a 3. It is known that a date stamp reading No 3 A was being used two days earlier on the 20th.

1956
A registered letter postmarked Tuesday, 3rd July 1956, with the “Club” date stamp that was not used the previous year.
1957
In 1957 a new “Club” date stamp was brought into use. It had a similar wording as before but set in double ring. It was intended for use on unregistered mail, however, if requested it could be used to cancel stamps on registered letters. Whilst a new design of date stamp was introduced for use on ordinary mail, the “Club” date stamp used since 1949 (except in 1955) continued to be used for registered mail. As registration was more costly and the interest in the new postmark was greater, examples of the old “Club” date stamp used in 1957 are uncommon.
