Well, having posed the question, and also bein insomniac as well, I spent some time trolling about the interweb. Found the RevellAG site to see pictures of the kit. SPS-10 and SPS-40 actually look pretty good, the 3"50 mounts also (a far cry from the blobish lumps on the box-scale kits I remember all too well).
The selection of the various items on this hull to depict any of the ten Z1 is fascinating. It has the single whaleboat, but retains the quintuple torpedo tube configuration. Now, I want to remember (and memory is a faulty thing) that USN had pulled quintuple mounts for two triples, as the use had changed from anti-surface ship to ASW torpedos.
But, I think I can put that down to the same way the WWII Fletcher is shown with the blast cab on the wrong set of torpedo tubes on the built-up model (and on the correct one i nthe box art). That's why we "do" this stuff, isn't ? <g>
If we could just get some on this side of the pond . . .
