I suspect I already know the answer to this question, but I'll hope and dream a little anyway....
I have a LionMaster Challenger and I love it. And I have no desire to plunk down the huge $$$s the new VisionLine Challenger in the 2008 V2 Lionel catalog commands. But, I like the idea of an auxiliary water tender that could add new rail sounds to my existing LionMaster.
The 1931311 Black UP auxiliary tender is probably not going to look right scale-wise with my LionMaster Challenger and tender is it? I suspect the answer is no, but if anybody has an example to post of what they would look like, I'd sure be interested. But perhaps now of these new Vision Auxiliary Water Tenders are "in the wild" yet to see such a comparison.
