I'm a little confused as to what Baltimore Oriole teams you want as you said you wanted World Series teams. The 1966 tem won the series but the Orioles were not in the 1976 series. The Orioles won the 1966, 1970 and 1983 World series and they lost the 1969, 1971 and 1979 World Series.
I'm just trying to clarify if you are looking for Oriole cards from when they were won the World Series, were in the World Series (win or lose) or that you indeed want cards for the 1976 team which was not even a playoff team?
