Matt Spencer reckons the top part of the Triumph pressure indictor screws onto the Norton bottom part, but I don't know where to get one. I've always been paranoid about oil pressure. My 500cc short stoke motor use to wear big ends very quickly so I had the journals hard chrome plated and reground. After a race the pressure indicator button used to stay out for quite a long time. However I suspect that very high oil pressure is not really necessary, as long as the big end bearings never run dry. The 500cc motor used to run to 10,500 RPM. A Commando motor usually only goes to 7000 RPM.
