I just received this one. It is a terrible attempt at copying a VLPP, so I love it. On the reverse the shield is small and head level. The obverse helmet and shield have deeply engraved lines. The legends are complete gibberish and it has a good bit of silvering intact; which, unfortunately, makes photographing it tougher.
