My little HW30! That was the worst gaulling I have seen on these, but sadly, it's been on every second hand '30 I've bought and worked on. I've one in the cave at the moment, where the bracket had been welded on back to front, meaning the M6 thread was in the wrong position to align with the stock screw. Sadly someone had carried on using it, so the front trigger screw hole in the stock had become oval, due to lack of clamping force.
