Can you supply the newer 2021 worm wheel for the Ref.6? The old version was white and the newer required version is black and a different shape so not cross compatible.

I have checked this for you and I can see that the part number you need is the following link: https://www.lsengineers.co.uk/worm-wheel-genuine-husqvarna-part-577-60-11-01.html
