As the cache owner, I can, with great sadness, officially declare ol' "I Think I Can" missing and presumed dead. I guess that is the inevitable fate of steam engines -- however small -- these days.
But there's hope! Even after a decade or so, I still have the 'copy' tag that came with the original TB. Once I find another small engine, I'll release "I Think I Can" II so the adventure will continue...
Maybe it'll be his long, lost brother. Or perhaps an evil twin!
Thanks to all those who helped (and followed) ITIC all these years.
