Wuffo Campy reverse thread crank puller?

C-Record and maybe a couple of other cranks from 10-15 years ago used left threads for the
self-extractor. This was a bit of overengineering...self extractors using normal right hand threads
had been introduced by Sugino several years previously, and the thread direction had never been a
problem in practice...so the use of the left thread was a "solution in search of a problem."

Self extractors often don't do the trick when the cranks are on really tight, so sometimes they need
to be removed and a shop-type extractor used instead. Campagnolo's use of oddball threading
necessitated the manufacture of the extractor you own.

You could probably get a fair bit of money for it on eBay.

One Campy carnk that required the reverse (left) threaded crank puller is the old C-Record from
1986-1993/94(?), like the one here:

C-Record, Chorus, and Victory (?) crankarms had one-key releases starting in late '80's. The
one-key release caps used left-hand threads to keep the caps from backing out when the arm was
being removed.

1984 and until 1994 Record, CDA, Chorus and Victory/Triompe...if it has a 7mm self extractor, it
needs a reverse thread crank puller-
