Western Milksnake???

I've been seeing ads for CB western milksnakes on the KS classifieds, and I was wondering what species they might be. I have never heard of them before. I have emailed the seller a couple of times but the must be ignoring me. If you know which ads I am refering to you might know why the seller is ignoring someone asking questions about their animals. From the pictures they look like they may have some thayeri mixed in somewhere. I've looked on the lampropeltis page and could find no reference to a "Western Milksnake"

Anyone else see these pics and have any idea what these snakes might be. They don't look like any milk that I am familiar with
