I'd like to see the tips of the brake levers myself; you may have the very first version (1992). Mine are first-generation; before I stripped the anodizing off, they did have the same logo as yours, but the blades lack the diagonal engravings further down the lever:
Note the funky tips of the brake levers - a sure sign these are first-gen. It's obvious your levers are fairly early as the bodies are alloy with the black rubberized coating. Mine are the same, although the black coating has been removed for a custom build.
