It's a long shot, but it seems like if anyone else would have decades-old panniers, it would be a Mustachian...
An acquaintance gave me these aged but apparently serviceable-looking panniers. The company doesn't seem to exist any more and of course there was no manual with them. I hooked them on satisfactorily enough, but there's this lever thing on the back that I can't figure out what it does.
So if anyone has or had these and can shed any light, that would be great. Aside from the lever, I'm wondering about things like whether it's better to hook the top hooks or the bottom hooks first and so on.
