I have an M.C. Gregory Model A mpc on trial. It seems to play very well, has great intonation and I'm inclined to keep it. I noticed, however, that it's asymmetric when viewed from above or below (i.e., perpendicular to the table). It has a slight bulge on one side of the beak, about halfway between the tip and the back of the beak, while the other side is straighter. The facing and tip rail seem unaffected. Is this unusual for this mpc, and is it anything to be concerned about? Is it an indication that it has been worked on inappropriately or is this a possible manufacturing defect? The serial number (low 01XX) and tip opening stamp on the table are sharp, but the logo and Model A stamp on the body are very faint, suggesting some wear. Also missing is any stamp indicating the chamber size. The bite area shows very little wear, with minor tooth scratches.
