1910 – Double Heads – the CTO’s

In RSCJ 279, there was an article by Robert Gallimore adding to the list of known CTO’s on Double Heads. This adds to the work already done in this area. In June 1987, Robert M. Gibbs and Stephen Reichek published a list of the Double Head “remainders”; stamps left in the London Offices of the B.S.A.C. at the conclusion of their operations in Rhodesia [see RSCJ 138 (June 1987)]. The devices produced for this operation were 1) double circle with arcs joined (DCAJ) for Bulawayo with six different dates; 2) double circle (DC) for Gwelo with six different dates and 3) double circle with arcs joined (DCAJ) for Salisbury with six different dates – the sixth date was only added in 2010, after it appeared in the appendices to Rhodesia – The Bi-Coloured Doubleheads 1910-1914, Edition XI by Stephen Reah-Johnson and Alan J. Hanks . The quantity of duties available varied from a low of 174 of the 2d duty to a high of 16,757 for the 1d duty. These “cancelled to order” Double Heads were regarded as being not worthy of consideration by many collectors when they appeared on the market. Since that time, numerous other discoveries have added to the list. In RSCJ 246/55, Alan J. Hanks and Peter Merrick, came together and published yet another comprehensive list. Since that date, a few new discoveries have been added, mostly noted in the Journal.

We now again publish an updated comprehensive list including all the new discoveries.  This list will be updated on a regular basis.  This will also act as a useful tool for the continuing and new collectors in this area.
