Hey, been following this for a while now, not sure if anyone is still following this, I notcied as I was researching "Philip Agee" the writer of the Cia book you received, that the "dragonlady" item is stamped 2 oct 1968
quote from wiki "In the book Agee condemned the 1968 Tlatelolco massacre in Mexico City"
So I checked and the massacre
happened on the 2nd of oct 1968 the same date as the stamps on the eletrical inspection to dragon lady
Anyway im havent managed to be able to find anything perticularly interesting (yet!!!) but thought other people might be interested
