Rich...the 1961 image proved my point earlier about 473 being the last to finally get its stack. I know it had one when it was in bumble-bee paint, but I was referring to the 60's when basically all the engines went to this.
Also I liked your shot of the K-28 with the pilot plow in Chama. Helps to hide some of those compressors on the front, which I guess some find attractive. I like the engines cause they are "Different", but have to say the K-36 and K-37's are much more to my liking.
By the way I did some "For Fun" editing today, and its uploading to youtube taking forever. Maybe later tonight or tomorrow will post it
to the board for all those with cabin fever!!!
