The second type was again on the mk1 and was held on via dove tail fitment, tbe sides were quite flat on the sight and this was fitted to 124 & 127 mk1 models! The third variant was also fitted via dovetail and the sides were curved, this sight had a rubber block between the dovetail fitment! And as already stated the rear sight was specific to each model 124 markings on elevation were different to 127 elevation markings! Hope this helps
That's right there are 3 types of for sight, where I disagree is that the very early MK1 sport had the same dovetail for sight as the 121.This was before the 121 changed to the FWB Sport Standard & the Deluxe mod had the hard plastic but pad.Soon after the MK1 like you say got the wrap around cross screw fitting.
