K-27 Books and Movies

[mudhen]

Just received my copy of THE MUDHENS by Dennis O' BERRY. So now I can see what type of weathering to do, light, medium, or heavy, or to keep it preteen. What a great book.
Now what to do to my Bachmann K-27 ? Chocks or paint. I have never weathered a locomotive before.
Like all railroads, I"ve seen different tenders on the 453 and even a snow plow. What year do I do ?. Decisions, decisions. Less than 5 months to get it ready for the May running season.
By the way, any one know of a good web site to see the 453 in action and in colour ?
Thanks in advance
