I am not so sure the Lichterfeld barracks and, the reich chancellry buildings are as specialised as you say. They are a neccessary for the figures that they released. A groupd of officers from Hitlers inner circle and some war hero's galland etc. The lichterfeld barracks was the home of the SS and, it would have been amiss not to have done it.
Now, I like my LAH collections and, the last few days of the war are of great interest but, IMO only, I would not have any interest in having a frail old Hitler parading through the ruined gardens of the chancellry patting idiot children on the head and giving them iron crosses for taking out some russki tanks. it was so bizzarre you could not have dreamt it up
What truly symbolises the end of the reich is the head shot to the fuhrer and Eva next to him tight lipped, when germany was free from his grip or, the soviet flag flying above the berlin capital.
Again, they would be sets which, would not be of interest to me personally now, a brandenburg gate would be another matter and, large yes, but, I would buy one at the drop of a hat.
