As SGV stated, rarity can be somewhat subjective , even though he has done an excellent job quantifying various models. The numbers help to dispel the B.S. However, "Beauty is in the eye of the Beholder ", and, that is a lot harder to quantify. Personally , I am gobsmacked by the GE ; to MY eyes it is the prettiest High Standard . Is it worth $ 800 ? A second barrel , even if not of a factory pairing , is still going for $100 ~ 175 on GunBroker /e-Bay / etc . Then the question becomes : is it worth ~$650 ( $800 -150 ) ? I'd be tempted , but , I have a nice one already . Good Luck !
