This is a PERFIN.
The question is whose
and when used?
Be honest. How many of you said this perfin was used by the Boy Scouts of America? Look at the stamp below. Now who?
The BSA letter perfins in the stamp was used by the Boy Scouts Association, Imperial Headquarters, London, England, until a postage meter was installed in the late 1920's. The postcard is addressed in Baden-Powell's own handwriting.
The next Scout related perfins did not occur until the 1957 Jubilee Jamboree (Ninth World Jamboree). A set of three stamps [Scott's #334-336, Gibbon's #557-559, Michel's #299-301] was issued to commemorate this event. They were widely distributed throughout Great Britain and have had perfins applied to them. A total of eighteen different are currently known to have been used on this set. Half of these perfin's origins are unknown and there may be others that have not been found as yet.

The most recent discovery of the 1957 WJ perfin use was found in full mint sheets in 1993. Covers with postal use are also known. It is now the assessment of several experts that these B---P perfins are genuine issues. Mr. W. O. Hawkins, Company Secretary at Slopers from 1939 to 1960 had this design as a perforated signature die. An example of this use ties both a corner of an envelope and the stamps. It is likely these stamps were perforated as a commemorative item.
There are no other reported Scout related perfins or any that were applied to Scout or Guide stamps issued in Great Britain.
