Re:
It is legit as it has the mottled 'champagne' (dull brownish colour that is bumpy and peals off a bit)
It is a later model as it's rivited. 12-32 spider.
Not the very latest as I cannot see the -I rear profiling.
No other looks like it, closest is M737 but that is compact (11T) and shiney chromed style silver.
