Why is that relevant? The IHB cars had W-corner ends for both types of car.

I didn't follow that exactly -- what do you mean by "earlier design" for the 730-B ?

The 729-B's were the 10-0 cars
The 730-B's were the 10-6 cars

You're right the 729 is IMWX/RedCaboose/Branchline and the 730 is the Intermountain. ( Or Athearn :-D )
The two sizes of the AAR design cars were built concurrently in the 1930's and 1940's.

"Since I bought NSC NYC decals there’s an IHB subject on the sheet I’d like to do.  I’ve found a photo of a car with 5/5 ends. Did Branchline offer this end in their 40’ boxcar series?"

They did not...but why use the Branchline model as a starting point?  What's wrong with the Intermountain 10 ft 6 in IH Modified 1937 AAR Boxcar model?  Despite the 1944 build date, IHB 10600-10699 (Lot 730-B) were built to the earlier design.  See Ed Hawkins' spreadsheet for details.
