Post subject:  Experimental Cancellations

Hello, I am trying to find examples of the 3 experimental cancellations described as SD3, SD4, SD6 in the excellent Collecting British Squared Circle Postmarks (PART II - THE LONDON OFFICES) in pages 8-9. Should you have details of any such items, please drop a line! Thanks.
