Volunteers originally had a form of Rigby rifling, later changed to Henry (denoted by a H prefix to the serial number). As to the matching numbers, I would normally associate this with parts that were hand fitted together, IMHO. If you have Pattern 1853 Enfield, if possible please check the rifling pitch and let me know - a tight fitting patch on a cleaning rod should give a good enough measure. Books on Burnside firearms you might like: 'Burnside Breechloading Carbines and Rifles' & 'The Burnside Breech Loading Carbines' both by Edward Hull. This code is invaluable in building an understanding of the production time line. I have a burnside carbine serial number 3032 on the receiver however the number on the locking block is 35680, this weapon does not have a forgrip and is octagon where a foregrip would be. If possible please include the date proof code from the underside of the barrel two letters and a number either between crossed swords or within a circle after the proof load information. Burnside carbine employed an unusual cone shaped metal cartridge for use in a percussion system. I'm keen to hear from anyone (use direct message for privacy if you wish) who will let me know the serial number of any Parker-Hale muzzle loading rifle they own / know of, along with its type (P.53, P.58, P.61, Volunteer or Whitworth). I have a database of over 600 Parker-Hale rifles. General Ambrose Everett Burnside was born in 1824 and graduated from the U.
