Jack The Ripper Hat Pin Record of Ragnarok

This is my version of Jack The Ripper's Hat Pin from Record of Ragnarok or Shūmatsu no Valkyrie.

A non-working mechanical model of the hat pin.

You just have to glue all the parts together, and paint them gold/silver/copper.

As a mention, you can just glue the engines wheever you'd feel them right.
