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.

This particular Douglas O-46A would come to grief on January 19, 1942, crashing in Millbury, Massachusetts. There is a series of photos within the SDASM's collection of the crash (link). www.flickr.com/photos/sdasmarchives/8091614443/ See: aviation-safety.net/wikibase/wiki.php?id=106018
