I agree completely that some of those very old ex-Pyro sailing ship kits are more than worthy of the modeler's attention. In another thread we've been following the progress of an excellent model of the Gertrude L. Thebaud (which the modeler based on an old Pyro version, but which could just as well have come from the Lindberg "American Cup Racer" kit). It came out beautifully. The Harriet Lane and the Morris-class revenue cutter also have enormous potential. The nice thing about those kits is that virtually all their weaknesses have to do with omissions, rather than mistakes. They were blatantly pirated from old Model Shipways and Marine Models kits of the 1940s, which were designed as sound but extremely basic scale models. To turn one of those old Pyro kits into a well-detailed model requires some additions (blocks, deadeyes, eyebolts, etc.), but little in the way of correction. (One howler that I do remember: the Morris-class cutter has most of its gunports represented in the form of raised lines inside and outside the bulwarks. The lines on the inside and outside don't line up. And the thwarts in the small boat in that kit don't reach the gunwales. All fairly straightforward stuff to fix.)
The big Lindberg "tuna clipper" is a reboxing of the old Pyro one, which was (I think) another pirated version of a Model Shipways wood kit. There was also a slightly smaller fishing trawler, pirated from the Model Shipways Hildina. (I'm sure about that one; I remember hearing Sam Milone of Model Shipways complaining about it - along with the Pyro diesel tugboat, which was based on the MS Dispatch No. 9.)
Lindberg (not Pyro) made another tugboat - with a wood hull and pilothouse (the prototype, that is - not the model) and the usual electric motor. The last time I saw it, Lindberg was selling it in a set of completely bogus U.S. Coast Guard markings. But it was a pretty nice old kit.
The fireboat, tuna clipper, towboat, and tugboat that were sold as a boxed set were, I'm 90 percent sure, the tiny 50-cent kits primarily designed for kids. As I recall, each of them had a couple of dozen parts; I think several of them shared the same hull components. I may well be mistaken about this, but I think they may have been issued originally with rubber band motors. (Wind up the propeller, put the model in the bathtub, and watch it go.) The figure 1/84 for the scale sounds wrong - unless it was a mighty small fireboat. Such vessels do exist.
I think the recent reincarnation of the LSU I saw may indeed have had the "LCT" label. "LCT," of course, is the wrong label for that particular vessel - though the LCT and the LSU had the same hull. The LCT's superstructure sat on one side, so the tank deck could run the entire length of the hull; the LSU was, in most respects, an LCT with the superstructure moved to the stern. That's the vessel the Lindberg kit represents. To my knowledge Lindberg never made a genuine LCT.
Here's another thought. For a few years Lindberg was selling some (not all) of the grand old Eaglewall British 1/1200 WWII warship kits. By modern standards they were pretty crude, but what fun they were.
I'm also wondering whether all this activity under the "Hawk" name means that some of the genuine old Hawk kits may reappear. That company's ship line never amounted to much, but some of its airplanes were quite interesting. Some of them have turned up recently under the Glencoe label (one is reviewed in this month's FSM), but many others are long forgotten. I wouldn't mind seeing the grand old 1/48 T-33, or the Kaman Huskie helicopter, or the Westland Lysander, or the V-1 (complete with interior detail - for 50 cents), or the Baka, or...well, you get the picture. Good news all around.
