The B1 is modelled on a locomotive that was actually used in Japan, but that comes from a family of narrow gauge Baldwins delivered around the world. This a quircky little locomotive that has a sweet spot. Find that spot and you've got a runner, otherwise hook it up behind something else that runs if you want it to complete a lap! That's a little harsh but there are more than a few people who have invested countless hours over many years to come up with a reliable locomotive. Maybe somebody would like to share their tips and tricks with us? Scott McDonald is in possesion of one that Yokohama Live Steam Club's Suzuki-san rebuilt and it is an example of just how nicely these little locomotives can perform.

It has a well populated back head for such an early Aster American prototype that includes pressure gauge, water glass, and clack valve. Each locomotive came with the "onion" stack shown above as well as a more typical American looking diamond stack.
