I know true collectors of old models of cars, boats, trains, and planes any even antique toys value articles more if it has the original packaging in good shape. Some people in the model plane and toys will just buy an empty box. O&R goes way back to WWII with their famous ignition aircraft motors. The cylinders on the compact is a blown up in size image of the old ignition motors. I still have a couple of those. They show up on eBay at times.
