Nelson 007 grip frame with small modifications, good shape with 12 gram screw and grips (has a hole). Left side panel has a hole which actuated a switch under the grips. There is a notch cut into the frame for the switch which has since been removed but you can see the hole in the pictures. Still works fine. This was on an Air Tech nelson I parted out. Has holes for wire stock. Perfect candidate for battel grips or replace the left side panel and they look almost new. Light rust on the steel trigger.
