Data from John Bourne, CE, Examples of steam, air, & gas engines of the most recent approved types (London: Longmans, Green & Co, 1878), p. 131.
Bourne's summary of the locomotives exhibited in 1867 includes this Borsig product. Locobase cannot determine if this was a Prussian Railways locomotive. Its dimensions are sufficiently different from other Borsig six-wheelers to merit a separate entry.
