Wow, Steve -
That sounds a LOT worse than the job Phil Reader had a couple of years ago helping rebuild Fillmore & Western's #14. I helped a little for a couple of weeks, when he was re-assembling the Stephenson valve gear (see the thread starting with [ngdiscussion.net]). IMHO, the crew that took the engine apart had been a bit over-enthusiastic, and had unnecessarily taken the valve gear completely apart. Anyway, Phil started to put things back together while I searched through a big pile of parts half-hidden in the weeds - mostly from diseasels - trying to find the rest of the pieces. I eventually lucked out and found the missing links, so then all we had to do was figure out which went on the left and which on the right, and whether the arms connected to the top or the bottom of the links. At least nothing was bent or broken, and the eccentrics were still in place on the axles!

p.s. If you tried to install Woodruff keys on all of the Missing Links & Eccentrics here on the NGDF, you'd probably run out of parts ...
