K Series Snowplows

OK. I'll take a whack at this.
We did cover this some months ago, but I'll try to recap the discussion's highlights. I'm sure others will rerail my effort if I go astray.
Some of the K-27's had been fitted with some, probably smaller version of wedge plow, according to brackets or bracket remanants visible on some of the engines in later years. 463 and 464 apparently at different times had a huge plow mounted which extended up to the headlight.
The K-28's were fitted with a larger plow, similar to those of the larger engines, but the top sheet had to be cutout for the air pumps. Since 9 of the 10 were in passenger service, much of the snow removal fell to them, as the passenger trains ran both directions each day.
The K'36 and K-37's used the most common plows. Most of them had smooth side sheets, some of them were made to fit over existing steel pilot beams. These could probably be swapped, and probably were, but it would take a long time to study them.
There were some unique charactaristics, such as the point bracket on 499. It was a large reverse design, which I have only seen on 499, over various later years. I don't reca;; if there was any discussion on the differences between plows that may have been fabricated at Salida, and those which may have been made in Burnham or Alamosa.
Many of the engines were not fit with plows each year. Lead helpers and road engines would have been the engines with the greatest need.
