Older H&R Huntsman .45 cal.

[bjgolfnut]

Hey,
     Picked up a older Huntsman in .45 cal.  Has the same type of RamRod but Breech Plug is different.  Percussion cap fits right on nipple.  Nipple screws out of plug and you need some sought of tool to remove plug.  Face of breech plug has two holes in in where this tool would fit.   Barrel is 26" and serial # is AJ305487.  Any info would be appreciated.
