For the sake of discussion.
I think the best you could hope for is correct lettering on Lionels current woodsided caboose which is close.
I have a couple of the MTH cabooses, IMO the details are better, especially with the more to scale grab irons on the ends. The truck spacing is off some. It might be difficult to get MTH to produce a caboose without a matching loco, but, who knows.
