Would the old Athearn 40' steel boxcar be a good choice for this

1994 about making this car.

Mark, there are several problems with this idea, apart from the
inherent crudeness and inaccuracy of the Athearn model (doors, lower
door slides, running boards, molded-on ladders and grabs, etc.,
etc.) First, the UP B-50-33 had W corner posts and round cornered
ends, whereas the Athearn model has square corners. Perhaps even
more problematic, the B-50-33s, like most other UP box cars of that
vintage, had what is commonly called ACR side sheathing - that is,
there was a vertical row of rivets centered between each of the major
rivet seams on the sides. We've come a long way since 1994, and
today I'd start with an Intermountain 10'6" high AAR box car kit and
add the ACR rivets using the Archer rivet decals.
