    It doesn't hurt. And I'll say this: even though I probably don't need one, I 
    still *prefer* a little vernier on the micrometer.
    "I thought those Russians didn't know what they were doing..."
    FWIW, Russian/former Soviet optical instruments have a generally positive 
    reputation, and I think it's well-deserved. 
    "I suppose much like antiques road show... the sextant was worth $10,000 but is now worth only $0.10 ;-)"
    Heh. Well, don't worry about it too much. Most sextants still price based on 
    their functionality rather their value as collectables. You haven't hurt the 
    functionality and you may have improved it slightly. Also, since new users do 
    ordinarily expect a vernier on the micrometer, you maye even be able to use 
    that as a selling point if you ever decide to ebay it. :-)
