Yes, I've got one (well, two) - last used on a Lotus Elan S3 a mate was putting back together.I used mine about 4 weeks ago. On a Astra Mk1 1300.
I even had to set the points, set the dwel and time it.
Until I bought a British car, I never needed one - everything I'd owned before was French or Italian from mid-70's vintage with electronic ignition - not a great deal to do once it was mechanically timed.
