I'm tooling up to build an early Peter Neihart and need to know the typical Lehigh ramrod size....I normally use 3 size thimbles for a tapered rod. I plan to use a rear entry of .350 ID, middle pipe of .375 ID and the muzzle pipe slightly larger, maybe .390 ID.....Anyone know details from original Lehigh pieces would be helpful....By the way, my barrel is 45", 1" breech and 50 cal.......Thanks ....Dan
