Warbirdguy et al--
I like these "what-if" threads...wistful though they make me! A Lib, eh? Hm. For starters, the choice of overall livery would depend partly on what Lib version it was. Ex USAAF/AF J? Probably one of the 5th AF ships with the Al Merkling nose art. "American Beauty" springs to mind with its Vargaesque pinup girl superimposed on a profile of Uncle Sam...of course the PC crowd would absolutely hate that one, which is all the more reason to paint a Lib that way!

Ex RAF/Indian J or L? Probably RAF CBI-theatre livery as the aircraft would have looked during WWII. Canadians flew Libs with the RAF in Asia (one of those Canadians, Harry "H.V." Smith, was the chief of the CWH Cessna Crane restoration crew years ago). Ex-RCAF GR-whichever? RCAF coastal livery, of course, as a Battle of the Atlantic tribute. LB-30? Perhaps that Pearl-period livery as noted above. That setpiece at an airshow would be very moving indeed. And it would be very tempting, if "my" Liberator were a fresh rebuild, to fly her first in a temporary primer-based leadship livery, before going to the permanent finish. Maybe one of Col. Stewart's Libs?
One detail that wouldn't be in dispute, in the (sadly impossible) event of my acquiring a Liberator, is where she'd be based. Any Lib of mine would fly in perpetuity from the Yankee Air Museum at Willow Run, Michigan. A very large portion of the B-24 production run originated at the Ford plant there and the museum has, of course, wanted a Lib "forever"...I so wish one could be brought "home" to Yankee.
