Speedmaster sale. It started

That’s a water hole by the one in the chamber so that would concern me. I would prob it with a small stiff wire or the tool shown. Then if it just a shallow divot (casting fault) I would probably grind it a little and weld and grind it flush. If it’s deep and I didn’t have a welder or know someone capable it would be on its way back.

The flaw in the chamber is roughly 2mm deep. The walls in the hole in the chamber is pretty sealed off, so probably caused from an air bubble in the material when it was being cast.

They are much more shiny than my X-heads.... I'm like a woman with shiny jewelry lol.
