K-28's on the White Pass and after their return

Sorry for coming into this discussion a little late, but I have some information to add.
First off, I have talked with several of the 770th men who operated and maintained the K-28's. Engine crews said they were okay, the shopmen thought the same. Contrary to popular belief, the Army shopmen did the best job they could. Very few people seemed to have actually talked with them, with many historians basing their judgements on the appearance of the equipment. Locomotives can look rough but be fine. The '28's were used very heavily until the arrival of the 190's as WP&YR Mike can prove from daily operations reports.
And yes, the locomotives were offered for sale after their return to Washington. The Rio Grande sent three men out to look at them, but as many know, this was a strange time for the Grande, with the railroad wanting to get rid of the narrow gauge but still having to deal with keeping it going. The men bought parts, rumors say driver sets and running gear mainly.
As for the #472, I've asked the Pueblo Ordinance Depot, (now under a different name which I can't recall at the moment) if there is a boiler on the property. I was told that all railroad equipment had been sold, to which I replied it was a stationary boiler I was looking for. I never got a reply to that, so it might be worth looking into further.
Hopefully this helps, I always enjoy discussions about the '28's after they went North. If only someone could dig up some photo's of the recovery of #474, (#253) from the Bay at Haines after she fell off the barge...
