Right Of Way Shay loco - what size curve?

As above, what is the smallest curve the ROW Shay will take? I know that many of their engines could run on 042.

042

That was a design masterpiece done by mechanical engineer, Ed Pinske  It had an extra set of square tubing in the linkage setup.  I remember the Sam Hong Sa (Korea) people coming into the Yellow Hall and starting to take close up pictures.  Bill Benson sent them on their way and told Dick Kughn not to let it happen again.

Thanks, Lou. I saw it in the Gold Hall all those years ago doing switch-backs on a special display, but never saw it on the curves on the layout. Much appreciated.
