Hello,
some folks were asking about Ju 52s and Ford Tri-Motors in 1/48 scale. Revell's Ju 52 has already been mentioned (and shown). I have a Schreiber-Bogen Card-kit for the Tri-Motor in 1/50, which I haven't gotten round to build yet (I'm too ham-fisted for card-models). They also offer a Handley-Page HP 42, and a Ju 52.
