Just picked up the bike earlier today and feeling super excited! They are indeed Weinmann levers. Definitely new tires as well. As far as the cable clamps, hoping to find some good replacements as they are currently just zip ties. It seems the cassette is Shimano so I'm assuming that's not original as well? Overall hoping to treat this as a little side project / restoration, but more importantly looking forward to enjoying riding it.

Anyways, I'll try to do a more thorough breakdown this week and hopefully we can pin down the year, thanks!
