Herewith, a British Philatelic Association handstamp not listed in Torrance and Morenweiser, incorporating the 3 Brenner Street address, tying a plain brown resealing tape on an incoming cover from the US. It appears that there is something in front of the /BPA, but I can make little or nothing of this. (The first letter may be a P, raising a suspicion of PTS. But that is mere speculation.) The tape is tied on the back of the cover by a London 16 July 1941 postmark. There are no Postal Censorship markings of any sort on this cover.
This would appear to establish the existence of an examination procedure different from that described in T&M.
Can anyone provide additional examples of this marking, or of other BPA markings not listed in T&M.
