Changing a simple coach

[Steamtrains]

Bernhard...Back in the days when the government did not try so hard to protect us from ourselves, we used to use a VERY thin paper and a substance then known as "dope" to cover model airplanes (stick & tissue construction...). I believe the materials for this might still be found. The so-called "dope" was an acetone based adhesive, and smelled much like acetate based glue. Perhaps these materials might still be found in Germany..??
