Dan, sorry man, but those are CH-53E's. The E's are completely different beasts than the D's. I have seen some D's about a year ago and they were also pretty grimy beasts, but they didn't leak in the same places. I wish I could tell you more about the D, but I haven't spent much time around them.
LemonJello, thank you, I appreciate it. I tried my best to give my model a dirty worn out look. I'm glad you like it. My next conquest is a Tamiya 1/350 scale Fletcher class destroyer. It's getting a conversion to make it the USS Dortch, which was my great uncle's ship. I've never done a ship before, but I think I'll enjoy it. Variety is the spice of life right?
