I probably more correctly should have said..It's possibly a Mantz bird.
Mantz purchased UC-67 39-36 in 1945 and sold her off in 1947. I looked through
the IMDB credits for "Cloak and Dagger" and Mantz is not listed. I also looked through
Aerovin's pages dedicated to Mantz and Tallman and did not find Mantz credited to the
film either...tho, could be a missed detail in both cases.
Thanks Kdmoo for the screengrab, always nice to see a Dragon in another life!
