Ie Ig 18 infantry guns

More 75L12 infantry guns 

This is a metal one, SHQ I think

Had this for ages and only just got around to tidying it up a bit. This one is by Hat

These two are my originals, 1/76 metal varieties by RAFM

Bit of a size comparison, not much in them really

Many German formations had these at the battalion level throughout WW2, which also included mountain and airborne variants.
