Weinmann 500 front and rear nutted brake assemblies, complete. Just replaced them with Shimano BR6600's. Original equipment on my '84 Peugeot PH10LE. Perfect for your restoration. I replaced them because they have never stopped very well, even when the bike was brand new. They'd be better for a museum-type show piece rather than actual usage.
With that being said, they're yours for shipping and a PM where to send them.
