Some weeks ago I bought this tinplate ETS reefer car. It must be a reefer since it is for meat transport. Special about it is that it is lettered for a large and well known meat processor and slaughterhouse in the Netherlands which existed until 1970. The railroad it is lettered for is the Dutch Staat Spoorwegen (state railway) which merged into the Nederlandse Spoorwegen (NS) in 1917.
