Lindberg is an old classic American model-making company, and we need to remember that, when we consider their kits. This set was first made about 60 years ago. For its time, it was quite the sensation. The average modeler was different, the average modeler's expectations were different. If we're looking for a shake-and-bake kit a la Tamiya, or the kind of detail we see in kits today, we'll be disappointed. If we approach the kit with that in mind, or as a bit of modeling nostalgia, then we're not disappointed.
Some of their kits weren't bad, for their time. And it depends on the kit and subject. Lindberg acquired kits from other makers, like Pyro, whose catalog has its own spectrum of quality.
Think of a Lindberg kit as a blank canvas, a starting point for a project in which you can use your imagination to add detail, and stretch your skills.
