I know of at least three conversions besides this one. One Shay in Washington, one in Virginia, and Canadian Forest Products had a similarly converted Climax. But unfortunately, I know little else on this topic.

Nice looking loco! Almost looks as if it was intended to be that way.
I recall seeing, many years ago, a ‘home brewed’ Shay conversion done at some logging company’s shop. It looked rather like some corrugated tin chicken houses from a poverty-level farm…
That looks like what would be one of the more conservative designs from the BerlinerWerke - would be interesting to see the Berlinerwerke dieselized enhanced Pacific Coast Shay.
