Luger Grips

[ShadowTX]

Would like to know if anyone has come across metal luger grips such as shown in the attached photos. The grips are not tin or aluminum, they are not magnetic and are hand tooled. There is a jeweler mark in the upper right hand corner of one of the panels, this mark appears to be a red triangle within a black circle. I was wondering if anyone has come across similar grips. I also wanted to know if the owl is a normal insignia or maybe family cress. If anyone can provide me with any information, I would be truly grateful.
