Hello I have a Armsport 5237 that is in pieces and is missing several pieces, It was meant to be a percussion gun. since im missing all the pieces for the lock except the plate I was wondering if someone could help me Identify the lock style so I could get a Flintlock and make this a flintlock pistol. I know Ill have to make a custom breech plug, etc. Any help would be appreciated let me know if I can provide anything else. Thanks.
