radial

Cool! Cubist!

A complete guess.. but maybe a propeller of some sort... mainly getting that from the right side... None the less, a cool looking thingy :)

Pratt & Whitney R-1830 (?) - It's obviously a cutaway display version of a two row poppet valve radial, but the lack of scale is frustrating. The cooling fins just visible on the cylinder at the center of the image suggest a Twin Wasp, but the rocker cover plates and tapered gear case are unusual. Possibly an early version, as most have bell shaped nose cases. Missing ignition harness is also misleading. Or is it an R-1535 Twin Wasp Junior? Most of these had reinforcing ribs cast into the nose gear casing, but I have seen one picture of a (later?) version without them.

1535 methinks, only missing the cooling plates between the cylinders. the two rows of cyl appear 'nested' as only i have seen on the 1535 in our basement.

Rosie the Riveter has nothing on this woman! She looks pretty tough!

I am so inspired by what these women did!

That is so awesome! I feel like more of that should be going on today.

I love the look on her face...

This title may as well say Women "can be" trained! It's so subtly of its era.

I dig the lighting in this one

Palmer definitely had a painterly eye.

Beautiful photography. Has a glamorous feel to them, like something out of Hollywood.

This is so great! Thanks for making these pictures available to the public!!

I love this photo and what it says: The good ole days of American men and women, working together, manufacturing with pride. In the U.S.A for the U.S.A !!!
