The Open 4CD was a predecessor to the current Open Pro rim and didn't have the welded seam or machined brake tracks that came on later Mavic rims.
I had a set of these rims built on 32 hole Ultegra hubs I bought in 1995. They were reasonably light and held their trueness just fine (more the result of a good build). They weren't particularly durable as the rear rim cracked through the brake track from abraison at about 12,000 miles but the front one lasted over 30,000.
You should get good service from them and at $25 each, they were a bargain.
