The correct Weinmann centerpull model number is Vainqueur 999. 610 and 750 refer to the reaches, with 610 front / 750 rear common on English and Japanese bikes. If you are dissatisfied w/ the stopping power of your vintage brakes, try replacing the pads w/ salmon Koolstops and the housings w/ modern low-compression stuff.
Yes! This is what I plan to do. Hopefully it doesn't lead to me replacing the brakes, but if it does, I'll be looking at these Tektros maybe.
