Ralf,

Yours is very much my own impression but does anyone remember the mix during that period or have any pictures of a train showing several wagons at once?

The works photos of new DB wagons in the 1956 Lehmann/Pflug reference book show almost all with plain DB markings. The exception is the Om 31 Umbauwagen by DWM Berlin where they were in the 1954/55 programme and the photo shows DR Brit-US Zone.

The 1960 supplement has also one photo showing the Europ boxed marking, on the Gmms 44 Umbauwagen.
