This locomotive was brought out around the same time as Boucher bought out Voltamp, and Boucher offered ex-Voltamp passenger and freight cars to go with it, with trucks altered for 1 gauge. As it turns out, this locomotive was in fact made by Bassett-Lowke. Whether Boucher commissioned B-L, or B-L made it for themselves and Boucher took the opportunity to market them in the US is unclear. What is clear is that at $275 in 1923 money, not many were sold. B-L also listed this model in their catalog, but with a few variations. The article by Claytor shows both the Boucher and B-L locomotives. The B-L has a different cab window design, steam cylinders and a longer tender than the Boucher version. However, in the 1927 B-L catalog, the locomotive is shown with the same cab windows and cylinders as the Boucher version:
As with most things that i own, this one is a bit strange with some unexplainable differences to other known examples. First and formost, it is coal fired, not spirit fired. The tender carries only water with a connection to an annoyingly intrusive water injection line into the boiler on the left hand side. The lubricator has been moved from inside the smokebox to a tank on the pilot deck. Bassett-Lowke describes it as having two trial cocks (to check for low and high water in the boiler), but these have been replaced by a proper sight glass. Some of these modifications are extremely professional and suggest B-L did it, and some are a bit sloppy suggesting aftermarket by a hobbyist.
