Ives first offered the 3245R in 1928, it was an articulated locomotive with the "short hood". The catalog referred to it as the St. Paul type. MTH has the 3245R in the 2005 catalog.
In 1929 Ives offered the 3245R again but this time it came with the long hood. MTH cataloged the long hood 3245R in the 2007 catalog.
