System DRAGER for ITS-911

[ITS-911]

My 1973 911 original handbook has a picture of a tyre pressure gauge which is a system DRAGER type. My tool kit seemed to have all the correct bits except for a tyre gauge, so found and purchased a system DRAGER gauge from a chap on the 911S forum. Just got it today and it's in lovely condition, but although close is not exactly like the picture in the 73.5 handbook. Have I got the correct one or should I continue to be looking for the "handbook photo" gauge? (Yes I'm a stickler for originality!). My 73 911 was an Australian Tourist delivery if this makes any difference?
thanks Geoff

Didn't have tyre guages in the tool kit by late 73 Geoff but good to have anyway
