Since there are experts here again who can say with 100% certainty that it is NOT 7040, I would like to emphasize again that this is clearly RAL7040 and everyone who does not believe that has no idea.
I must correct you to my deepest regret, I certainly do not want to offend you. For the sake of truth, it is not RAL7040, but
RAL 000 65 00, Mörtelgrau, Mortar grey. There really can be no doubt about that. ;-) (It raises the suspicion that you receive a commission for selling the paint RAL7040. ;-) :-) )
