Look like Bologna to me. On the steerer it should have some letters stamped such as CM/TB (CrMoly Triple butted)which would mean they are the Lite versions. I think the standard Bolognas just had CM/SB (CrMoly single butted)
Had a little look tonight. The black pair have TB as you stated which I assume means they are triple butted as I expected. The purple pair don’t have anything apart from 1993.
