Hi all,
After seen grease traces over the frame around the frame, took a look and found the top bearing shot.
Had a quick look at replacing the bearing but could not find an exact match, 42 od 30 id 6 wide
Anybody got a suggestion as to where to get a set?

either ID it (see Parktools) or take it to a bearing shop.
is it a IS ZS or EC?

This drove me mad when I was looking!

You are basically looking for a 1 1/8" Campagnolo (sometimes called Italian) Integrated Headset bearings set 45/45 (I think these are the angles on the bearings)

This is what I purchased... (whole headset)

And one on CRC:

These bearings look similar:

Or maybe the WCS version:
