Alfa 3.0l engine cylinder liners.

Hi Ian - Gerry sells a moulding that's the same as original and uses the lenses and bulb holders from a Mk2 Ford Escort but it's fiddly to make it all fit and you end up with thin fiberglass/perspex. Your's isn't one of those!

If my memory is right one of the options I looked at back in the day was from a DAF 33. It's a bit chunkier than the Stratos one and the back of it was slightly hollowed out? Looks like yours I think but I can't find a picture of one on the web yet! Let alone one for sale anywhere!

You're right Guy.
It's a Volvo part (who took on DAF's cars) by the looks (part number 3269813):
