    If the one you're looking at is the over-priced one on the UK site, 
    190312688318, it does has an automatic averager, as does the one for sale on 
    the US site. These are excellent instruments that give good results. For use 
    on land, the Mark IX may have advantages as it does not have the extra weight 
    of the clockwork averager. It has a six-shot finger-operated averager. The 
    latter is fairly easy to put back into order if disordered. I would not touch 
    the IXA averager without substantial clock-repairing experience. There is a 
    reconditioning manual available (mine!) if need be.
