Thanks for the responses!
Jim Roeder's book has been a fantastic resource. Seems like just the lead ships got painted. 01, 13. From the text, the author received images "showing a third Invader ('08' 44-34555) in the process of receiving the groups blue color at Machinato. The pictures show that the rudder was painted blue, while the remainder of the tail had yet to be resprayed." Page 184.
It's definitely a basket case, but it's a worthy airframe.
I'm looking for wartime photos of any A-26 operating with the 319th, blue tailed or not. This seems to be a hard unit and airframe combination to find good photos of, due to the rush into service, and end of the war.
