Not much made then, that's half the number of Hafthohlladung, which was also canceled in May 1944 due to replacement by the Pzfaust.
As for the Pzwurfmine, though I could def see them getting issued to LW Feld divisions, considering the menagerie of gear they got, it just does not seem common enough. Maybe someday, as a special pick up for battles where Lw Feld divisions are, but that's up to the devs.
