Enterprise links modeled on the Ulrich car (you could of course
the Ulrich operating-rod parts, and substitute brass wire of
diameter or so). Also, in the early 1950s, GN began to remove
those heap shields, so it may depend on your era.
The GN cars were also a little bigger in cubic capacity, due to
sides, than the Ulrich car, but that is a lesser concern if you
a model that is "close."
