I'm impressed! Firstly at Kurt's eye and then southpawbostons's use of CAD - I'm a complete novice.
I've measured the angles as best I could (by holding a clipboard and paper against the frame and tracing the tube lines, then measuring the angles) and find the HT to be 75 and the ST to be 78.
Kurt, what does this mean?
