Hi T-Mar, I found what I believe is one of the very early Centurions this morning at an auction and I grabbed it.
Although I believe that this Centurion Omega is not at the top of the pecking order, it has extremely fancy lugwork and bullet-point seatstays compared to my Sport DLX.
It has a nice metal head tube badge as well.
I'm guessing it's just Hi-Ten steel. R derailleur is a Shimano Tourney. Front is a Suntour 7. Dia-Compe drop forged center pull's.
Notre Dame fans would love it because it is an attractive all-emerald green w/ gold-leaf style lettering.

Serial #: IH28649I and is followed by the Omega-Centurion symbol

Do you need more photos than this one??

My guess is somewhere around 1972 **********
