2017, April 27. Note that these triangulars have the point upwards and are ON the stamp. There is another postmark that has the point downwards and is (normally) never on the stamp.
There is much confusion and guessing about the triangles.
Here I only consider the "point upward" marks.
Here is a trustable text I have found recently :
"These triangular obliterations began in 1895 to be used for bulk cancelling of "imitation" typewritten circulars (at a lower postal rate). Originally they were singular handstamps. But at the beginning of the reign of Edward VII machine cancellation was introduced and the c.d.s. (circular date stamp-note P.D.B.) usually found in such cancellations was replaced by a triangle." (M.R. Hewlett, Wiltshire, 1971, "picton's priced catalogue of british pictorial postcards and postmarks 1894-1939)
