discussing about these relevant elements of the coupe´s style and discarding new repros including those available from BMW dealer (those where the blue is in fact violet), i have discovered four different versions so far:
roundel in aluminium, raised letters and painted, short studs unthreaded
roundel in enamel, flat, long studs threaded
frame in unknown material massive, chromed
frame in aluminium hollow, anodized
i do have some pictures:

anyone has more details about dates and so on for each versión ?
thanks
