I built the first of my kits as HBW too, because I served with a couple of guys who had been Sonar Techs on that ship earlier. The kit comes with both types of missile launcher, so you can build either the earlier or later members of the class.
If you really want to be a nit-picker, the members of the class had variations on the radar fit, with some having the more common-looking eleptical SPS-40 radar antenna. Henry B had a rectangular antenna on the SPS-29 or 35 system. And on the fantail, the white outlines for the helicopter unrep drop zone were shaped differently from ship to ship. There are enough variations in the class that I thought I would build a few more of them, but there are so many other ships to build...
The original Skywave kit was waterline only, while the Dragon kit has the lower hull option too, if that matters to you.
Good luck
Rick
