Iowa auction gem

I'll be heading south [for me] to my grandpa's farm auction this weekend. He's getting rid of a lot of rusty things - most of which I don't even know what they are. But this gem ... well it's pretty darn obvious what this is.
Wonder if it still runs.
Wonder if I can get a sidecar for it.

he's also auctioning off his 1960 Chevy Impala - that is one cherry auto
