I was inspired by some of the retro radio models people have done with MOI and posted about here on the forums, so I thought I'd have a go at it. I did a bunch of searching and found some examples. I picked the Continental model 5R30, 5R30A, 5R31A, 5R32A, and 5R34A as examples from this website, http://www.radiomuseum.org/m/hallicraft_usa_en_1.html and went from there. This is still a work in progress (I hope to model some internals as well) and I've taken a few liberties with it as well.

Modeled in MOI (except for one stubborn fillet done in Rhino), and rendered in MODO 601.

*EDIT* added internal detail renders below
