Looking to replace the old style brake levers (not the brakes themselves, just the levers) on my '80 Nishiki. The front brake is center-actuated; is it a "V-lever" or is it a center-pull cantilever?"

The rear is activated from the side; I assume it's a standard "caliper" type brake.

Looking up "V-lever" -type brakes, it seems to be described alternately as a (1) more modern brake version, or (2) an archaic brake type that should be avoided. So I'm not sure WHICH front brake I have. Pic below.

The reason I'm posting this is because apparently, the V lever type requires a longer pull, and thus a different brake lever, than the side pull. From "Bicycle Touring Review:"

There are a range of different braking systems out there for bikes. In terms of rim brakes, there are three main types;
caliper (on most road bikes)
centre-pull cantilevers (cyclocross-style)
the more recent linear-pull cantilevers (V-brakes)

The V-brake appears to require a different lever, with an internal system that pulls more cable than a standard lever can. I'd like to be sure what kind of front brake I have before ordering a new lever . . . and I'm wondering if I'll have to order the front brake lever separately from the rear (side pull) lever. Thanks!
