I think it's one of the big Japanese sail training ships - the Nippon Maru or her sister (whose name I've forgotten). All the yards seem to be missing; that's probably why the vendor thought of it as a "steamer."
Imai used to make several Japanese sail training ships on different scales. I've never sorted them all out, but I think this may be one of them. It's also entirely possible that some other Japanese company has kitted them sometime or other.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
