Data from Steam Engine List compiled by R F Dole 2 January 1959 and Gene Connelly Roster, both supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange collection. Works number was 2807 in 1892.
Locobase added a 0-4-4T Forney tank as entry 10023. The extensive details available from the source didn't include the builder, built date, or railroad, so Locobase could only say that it was a typical example. Dole's data show that this Maine woods tank was very likely a sister, or at least a cousin, to Matthias Forney's eponymous archetype.
The S&M didn't operate the 105 for very long before trading it in 1896 to the Maine Central for Portland works number 189. (Also numbered 105, the Portland 4-4-0 was originally bought in 1871 for the Portland & Ogdensburg as their #5, rebuilt in May 1891.)
The MEC operated for amost 25 more years before scrapping it in January 1920.
