Actually, I think it's ment to be used for Dragon's 234/1, as well as they made a similar set for the 234/4, which I'm building right now (as for the latter, there is a small brochure which describes it into the box: it features PE gun shield plus other details). Also in this case, there are new sidepods with more hatches, which allow you to depict an early version of the vehicle, and decals for further liveries.
How much does it cost?
