Thanks Mike, so if I offer it Ill assume the one I have is correct spec from the very earliest RHD 911 in May 65 through until that supercession for H1 68S even though date code points to item being a 65 model year item.

H1 and H4 are familiar descriptors is there an accepted term for these or are these simply known as Bosch 7045/4487 based on the lens number
