Old or vintage Moro kris? Which Moro group?

[Sajen]

I have acquired this later Moro Kris since I always wanted such a kris with a scabbard and hilt with these MOP plates and this in a better execusion and especially complete without missing plates. Have found it!
But I have several questions! Age guess? Second World War or short after? Sulu? And why is the show side different from antique examples, a question I have already long but never asked for!
