These are the levers that work with V brakes.

In my search I found that Cane Creek makes a similar set of levers.
Those V brakes are pretty ugly with corrosion. If you decide to stick with V brakes, but choose to replace those, figure out if you want fenders on the bike first to make sure you get enough clearance when you do your brake shopping. You do not want to buy brakes and then find that the brake and fender do not play well with each other.
