I checked my UA72200 image and instructions against the image and instructions posted on the Modelcollect company website for UA72211, both covering the B52H . As Modelmkr points out, UA72211 does not include: The "Z" fret, The Photo-etch weapons wings fret, and the Unit markings. Moreover the B52H UA72211 image on the box, while similar to UA72200, top does NOT show the underwing pilon with weapons mounted - whereas the UA72200 (my kit box top) DOES show the weapons pilon. So, if you want more "goodies" go with UA72200 - if available (it may now be superceded already).
Cheers
