Indeed, but the DRL DRGM was a copyright for the design of the badge and it came on no matter who made the badge. I have seen 3 variations of EK with this, all Meybauer made crosses... then this. There is an off chance that another maker used these... but so far none spotted... and then... why would they bother? If i am not mistaken, they would have had to pay Meybauer to use their copyrighted simple nut designed by them? Easier to make a nut of your own and pay nothing ? I would guess very likely Meyerbauer, with a "Never say never" possibility that someone else may have used these. (Has anyone seen one on a non Meybauer product?)
