Cool If I happen across any yellow or red ones I'll steer them in your direction.
I tend to scour ebay for part sets and then refurb/service and combine them.
I do have some original yellow RLs, but they're a bit too scruffy for your needs I suspect!
Funnily enough I was thinking for getting more modern Magura rim brakes and retiring the TWP’s (I use these with the Tomac red calipers). I have a new set of HS 11s but really would like the HS 33s.
