old art deco vintage Burgess Vibro-tool electric needle engraving pen

Old deco vintage Burgess "Vibro-Tool" electrical engraver with great art deco name plates. It has a plain steel needle engraving tip and hard plastic case. We plugged this tool in and it runs. There is wear and scratching to the case, as well as cracking / splitting at the corner near the cord (please see the pictures). An owner's name has been engraved in the case near the front.
