By coincidence I have a cam that looks exactly like that so I attach a photo of mine.

For some strange reason the drop box image is a negative.

Thank you and I can see the advantage in weight reduction with that bucket type arrangement.

I have another question. Was there a flap lifter setup someone made for a Norton twin where 4 long narrow plates are hinged near the bore so the plates are riding on the cam lobes and only the plates are between the cam and the pushrod? The pushrods being located in recesses on the top side of the plates. Or is this just one of my fantasies?

The drawing for the Domi racer bucket style follower indicates other shape the tip was Stellite not Delcrome C that was used on the standard followers of the period.
