Thanks Rusty! I have several of the "Kalamazoo" line specialty pieces in my large scale roster. I believe they were marketed under the Delton brand. This looks like quite an exhaustive and interesting historical treatment of the various companies (mostly headquartered in Kalamazoo, MI) , with many beautiful, large color photos of the trains themselves. I didn't realize that these brands had so many common origins!
Hopefully, here's the link to:
