There were two fully tracked protos as well and those made it to the Eastern Front

Now that one ( Pz.Sfl.Ic ) is very close in concept but it is described as " a fixed open-topped superstructure " mounting a 5 cm Kanone L/60
but as noted in the original post the Pz.Sfl. II had it's 75mm gun " mounted in an open-topped, low-profile
turret "
If anyone knows of a source that gives hull length and width It would be helpful but not critical and that example I provided was a WAG for length and width which is probably within a pixel or two of being "close enough" but it would be nice to have actual data
