Here's a picture of the Martin bits. They fit together and make a virtually smooth bore. The Mammoth is about 15 cents flat with both bits in use. The pistons are .003" undersize and are off to the plater this morning. I'm hoping the pitch comes up with the new valve job. If not, I'll just make a new one piece neck and squirrel the bits away.
