I think it is a Thomas. Re- stick the decal with Solvaset. Be very careful, because Solvaset will melt the decal as quickly as it sets it.
But you can find new decals - those are Walthers, and still available if you know where to look, and Protocraft has a really good set. And I have (maybe) white ones with black outline.
I finally finished my new Lobaugh - photo above. It has a few blemishes, but I am now happy. I may do one more.
Thomas tank cars are nice, but not nearly as rugged as Lobaugh. The wrapper is .010, and they use a lot of die cast parts. I usually reinforce the tank with brass tube inside.
