I am looking for help learning more about this pair of pistols. First, I know very little about flintlocks. My brother-in-law acquired these about 10 years ago and recently gave them to me as a gift. They have many of the same markings and there looks to be writing or Roman numerals across the headband of the crown on the side of each weapon, and the text looks to be similar on both. One of the handles was repaired with a dowel, and the other is loaded. I would appreciate any help in learning more. Thanks in advance!
