Hi thomas, this plan is for the Halford (and not Hanford) with the catapult, not really interesting for me who seek operational ship :
"The Halford was one of 5 Fletcher-class destroyers which were modified to have a cruiser catapult installed on the aftersuperstructure replacing the #3 5-inch gun. This was an experiment to provide aircover for convoy support. The experiment was not successful, and the catapult was removed and the ships were returned to Fletcher-class standard."

By the way there's plenty of plan for Fletcher class destroyer (1/96 and so on) but having a real 1/72 plan is time saving, you don't need to re-calculate everything, and for DrPR I prefer to work with the entire model in one paper although I understand your way of work.
Anyway, I'm sure I will solve this problem when the time to build will come, maybe some sellers will accept to convert one of their plan into 1/72.
