Looks like a new mistake to me, they dont look like the long range tank on the modern 47/57 which only has a tank on one side. 145 has that in the photos above.
It should look like the photo of 284 at the top of the page!
As i said they have made a hash of it, my Bachmann 47408 looks better than that.
Real thing is here.
