Not exactly. The most common Hungarian light field artillery piece in WWII, the 14 M 10cm howitzer was the same short barrel howitzer that was used in WWI.Hungarian 100mm 14M is the same as Slovak field Skoda houfnice vz14/19 and Italian Obice da 100/17 modelo 14.

The Slovak vz14/19 version was the one with the lengthened barrel for increased range. But you are right, it is basically the same unit so I will make new icons, one with short barrel and one with the lengthened. The Hungarian howitzer, though, should have a range of 2 only.
