The one with the '49' marking seems to be Danish. Attached a picture from a Danish manual. It was desinated "0,6 kg øvelsesgeværgranat M/49" in Denmark. Later these Danish practice ENERGAs had a blue body and white model number. However, I have never seen white tubes and fins on the Danish models. Is it possible to show detailed pictures of this one only?

Hello Antoon,The Dutch HEAT rifle grenade was the NR 4 with nose fuze NR 37. The sight was the NR 17 and was used when fired with the FAL Rifle. The first marking was green with a red band and yellow text. The newer marking was green with yellow text. The practice with the chalk head was the NR 28. There was also a full metal practice version, blue with white markings. The pictures with the rifles are from the Dutch Institute for military history (NIMH).
Leaflet,Hello Antoon,
It must be a Slip of the pen but the practice version with the chalk head is the NR 18.
