These aren't new engines, they're models previously produced by Aster: the "Glaskasten" and the Kiso Forest Railway 0-4-2T. Methinks they're testing the waters to see if there's enough interest to make it worthwhile to re-issue them. I'll bet the tooling is still sitting in a box somewhere, so there's relatively little up-front expense if they want to build a batch of a hundred or two. Smart move, IMHO, in this lousy economy.
