I hear that Bachmann will be releasing a Lilly Belle train set in March.  I've been working on a historical diorama for our public library based on an 1888 photo which includes a virtual twin of the Lilly Belle.  I'd been facing the prospect of building this loco entirely from scratch, but if this Bachmann model is accurate enough (true to scale in most/all significant respects), then I'd be interested in it.
