Wreck with 319 for the movie on the Silverton Line

I saw a clip today showing the big head-on collision at MP 475 for the movie Denver and Rio Grande. I searched the board but could not find the info I saw previously about this wreck. I know one engine was 2-8-0 number 319, and another 2-8-0 I think numbered 268 in Bumblebee paint. I believe this was another engine renumbered but cannot remember which number it was. Both were scrapped since the real 268 is in Gunnison. So what were the numbers of both engines, and anyone have an exact date for this wreck scene. We have a 1964 photo runby at this location and will be inserting a still from the wreck and want to get the facts correct. Thanks in Advance.
