News to me about the rifles, I'm no expert ! We didn't visit Spandau, it was still in use, for one prisoner...
The oddest thing about the trip was nighttime, in the west Berlin was lit up like a Christmas tree - in the East almost all the lights went off.
Saddest ? Pensioner's bridge, where the elderly were allowed to leave the East and rejoin families after 40+ years, they were seen as an unnecessary burden.
Awesome ? Passing the Fuhrer's bunker, or the Checkpoint Charlie museum seeing the equipment used in successful escapes.
