Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 72. Works numbers were 16634-16635 in April 1899.
The Brahestad operated on the northeastern coast of the Gulf of Bothnia.

The animator's railroad website -- [] (2 April 2003) -- says that this little tank was privately operated for most of its working life. Indeed, when the VR gained title to this engine, it took it out of service.
The photo shows a balanced profile with the steam dome sitting over the space between the two driven axles and sand domes ahead and behind. The snowplow pilot and vestibule cab are Finnish standard, while the stack resembles a martini glass.
