This model dates back to the early days of N scale (late 60s / early 70s). It was originaly imported by MRC and later on became part of the Minitrix "Old Timer" series.
I'm told that this model is actually a good representation of a rebuilt Seley composite hopper. Originally built in the the very early 1900s, they were rebuilt by the Delaware & Hudson into triple hoppers in the 1920s or 1930s. Said rebuilds were in use until at least the early 1960s.
