Obverse looks OK to me apart from some lack of detail to some of the veins (which could be wear, although I remain highly skeptical of how a chest-worn award on a disabled man could ever achieve such 'wear'). I'm guessing you don't have your example in hand? If you do, accurate measurements and weight could prove decisive as a cast copy is often slightly smaller in dimension to an original .
Having said all that, please compare to my own M/100 example. I don't have an image of the reverse oddly enough so will try to rectify that over the coming days. This example was vetted and found good by renowned SA badge collector and member 'Gravedigga' who sadly no longer frequents either this forum or the WAF.
I think it is good too.
