Haha, I've got one of those levers. That's the HS22 version. The red ones, which are actually red, unlike that which is fluorescent orange, is the HS33 version, which looks like an 04 HS33, because it is one. Its got a bigger piston size I think. It's internals are not compatible with any other HS brake. You can get them if you like, it works. £30 if they're good, less if they're shite.
