You are correct, General Harmon's B24 had no guns, extra radios, extra fuel capacity, and a "cabin" for meetings, etc. It was not painted (or painted silver/gray) and was called "My Ever Lovin' Dove" (Gen. Harmon's wife had "dove" as a nickname).
I will scan a bunch of photos at the office as soon as I can and get them posted. I would be very grateful if I could find someone to skin it.
Your problem is going to be it was an unarmed transport there for not allowed under HTC rules as others will eventually point out to you.
Along with some other issues such as never dropped bombs & so on & so on. I would suggest you contact HTC direct & ask for an exception as it is a family situation.
I don't think any of the skinners will do it unless it is given the OK by HTC.
Unless you just want a personal skin for your own use offline?
May be better off finding more on the other plane.
