Brisbane R in oval registered handstamp

Brisbane post office opened in April 1830
Given the volume of mail that went through the Brisbane post office, there are numerous examples of this handstamp, enough for it to be considered common. However locating individual examples on piece or cover is fairly challenging and so I have given it a Rare rating. It was usually accompanied by a Brisbane registered datestamp. 

It is seen in black from 1892 onwards. From 1909, but only when used in conjunction with a Brisbane registered label, it is in blue. I have provided a representative sample of the handstamps on piece and cover in black as well as all those seen by me in blue
