Looking for an ex49 aheadset colour not important
This should be external aheadet an the lips on the bearing cups 49mm
I think it's the same as a 1.5 to 1 1/8 converter aheadset that's basically what I need
 
This is what I have. It's a brand new nuke proof warhead. It has no size markings, box got trashed so I've not got that. However, I do have a nuke roof cup marked ex44 which slips inside the warhead cups which should confirm it's an ex49.

I bought it in error a year or so ago thinking it was for a tapered steerer, but it's for a straight 1 1/8 fork steerer. Ended up with a Chris king

Can you measure the part of the cups that sits in the frame please
How much are you wanting for it
 
Here's a pic. The digital bit on my guage is broken but the outer cup diameter measures 49.

Research suggests the cups are zs49, zs standing for zero stack. Same as an ex aside from bearings are inboard the cup rather than outside, great if you want to solve a short steerer tube or in this case, run 1 1/8 bearing inside the cup rather than outside.

I'm running a king version on a build which initially had external cups, though in my case with a tapered steerer.

Pricing online seems to be £20 per cup plus postage, how does £30 Inc UK postage sound?

That is the diameter of the part that goes inside the head tube. As it's a zs headset, the external cups is more of a lip if you get my meaning.
 
After much research
I now know cannondale use a 49.6 mm cup this frame is approx 2006 / 2007. It's a coincidence that in later years a 49mm headset has appeared
I ve managed to source the correct ( I think) headset
As the modern alternative would be 0.6mm smaller
