If the front mech is braze on - I have what I believe to be, a Record/ CdA mech as seen on my Merckx.
For the deltas, you do realize that the current sale prices of graphite versions can far exceed silver versions?
I also have some non aero top condition Campagnolo levers but without hoods...
I do remember info a while back that quite a bit of the graphite stuff went for strong money but for ease as much as anything a straight swop would do me.
The front mech is a braze on so would be interested in your Record/CdA one if it's available. Looks like I'm sorted for brake levers though.
