Came across this in Great Barrington, MA this past weekend. The owner's doing a great job restoring it, my pics don't do it justice. He's got the canopy for it as well.
Not too much more other than it was captured by the Japanese during WWII and spent the next 66 years in Asia. He found and bought it in 2009 (he's an Asian Artifact importer/dealer). It's mostly original parts, it was in particularly good shape when he bought it.
