Sorry, I know this isn't the typical post that this sub gets. I've only found a few of these for sale online, all for quite higher prices. Apparently it's also on display at the Henry Ford Museum (https:// www.thehenryford.org/collections-and-research/ digital-collections/artifact/291979/). That's about all I know. Anyone know why it's listed for so much ($400-2500) on wherever I can find it online? Any input is appreciated, thinking about going to scoop it up tomorrow. Thank you!
