MBNA sourced the kits for the US version cars in the US (not sure about the early years, but in the later 70s from a company called American White Cross. The reason was that the German kit did not comply with US regulations, since it contained some medication - for which the dealers would all have to be licensed pharmacies - and deadly weapons, like scissors for cutting the gauze strip. The US kits therefore were largely different from the rest of the world.
