The Stowaway is a nice unit. I've owned probably 7 by now in various speeds and configurations, and am down to 2 matching ones now. Here's the twin to yours. I refurbed it to flip it (really needing to downsize the collection). You'll see the fenders and chain guard that came on them.
Yep, the fenders on mine were broken so I took 'em off.
I also don't have the little wheel on the bottom that allows you to roll the folded bike around, but at least I have the rack which I forgot to put back on before taking the picture.
Yours are definitely nice, just about every chrome part on mine was heavily peppered with rust and it took hours of scrubbing with windex and aluminum foil to get the rust off.
It looks fine from a few feet away, but not so great up close since you can still tell where the rust was.
It would be nice if it was in better cosmetic condition, but since it was free I don't mind.
