Seem to have lost the first effort to post, hopefully this doesn't show up twice.
The link below is to another forum where the redesigned breather is shown. Redesign needed for some '73/'74 crankcases. Not sure whether this one is available through CNW or just direct from Jim.

This is one of Jim Comstock's developments. I believe marketed in the US via Colorado Norton Works. There is a thread on the Commando forum.
It might still be at the development stage as there was a problem with differing internal castings on some crankcases, making it not always a bolt-on mod for some engines.
