[CR]80s Ochsner question

Hi all,

I live in Lexington KY and have several bikes. The bikes I have that are relavent to the group are a 1975 Woodrup Star Trophy Model, Mid 80's Woodrup, mid 80s Puch Mistral Leader, 1983 Mercian Touring bicycle, and last but not least a 1980s vintage Ochsner. I have a quick question that I was hoping someone could answer.

Were all the 80's Ochsner's built of

COLUMBUS AELLE TUBI SPECIALI IN ACCIAIO AL CARBONIO MANGANESE.

Or did they use other types of steel? The tubing decal on mine is gone so I'm curious.
