    Please accept my apologies for no pricing. In all fairness, as I =
believe that this is probably a pretty rare set and I doubt I will run =
across another in my lifetime, I would like to accept a trade on this :
    EAC R-390A late model cherry set,  original meters, no water or =
restored pieced together types, etc.I believe that would be a fair trade =
and would keep money out of it. Thanks,Byron.   =20
