A little bit more on this. The pivot pin was turned and threaded and then I started the operating lever from a piece of 6mm thick aluminium mostly with a hacksaw and files. The slot for the ball bearing follower was milled out using the little Proxxon mill and the end profile was finished with some filing buttons I had made for finishing some pipe flanges. A quick check showed that I needed to relieve the lever a little more so the follower roller was always in contact with the tappet.
Best regards

The next step was to turn the bronze bush for the lever. This was made from a little offcut, bored and reamed 4mm in a collet and then pressed onto a tapered mandrel for finishing. The washer from the end of the pivot was turned from a piece of 8mm steel of some sort. Then came the problem my 6mm aluminium was actually 1/4" so when I put it together there was negative clearance  :( A bit of filling solved that and finally I turned the follower pin from 2mm silver steel.
Next up the inlet union and delivery valve.
