Mark, Have you measured the bore's?

Dave, I do not have the proper equipment for measuring bores. In fact, UPS should be dropping the barrels off today or Monday. They were restored by Brad Bachelder. He may have included a set of 'before and after' measurements. The barrels were literally sewer pipes and required a bit of reaming to clean them up.

The Parker Story states that the 'diamond P' is unknown. My 1877 Twist barrels have a 'diamond P' on one barrel, ahead of the flats. My 1879 Laminated barrels have 'diamond Ps' on both barrels, AND a 'plain P' on the right flat next to the weight. Is the 'plain P' supposed to indicate Parker made barrels, or is it the 'diamond P'?
