A flintlock pistol ... with a Portuguese lock.

Fernando: Thank you for the additional photos. Most helpful. Some additional observations:

STOCK: The lock mortise now confirms for me that the stock was made later to accomodate the older lock and barrel. While the lock and barrel have seen a lot of use and re-use.
BARREL: Yes, now you can see where the percussion bolster once resided. But it appears there was no effort made to fill in the larger hole and re-drill a smaller hole for the vent. Unless it was filled at some point, and just burned out from usage. (?) I sure would not want to be standing to the side of the lock while firing. LOL
LOCK: This is the first first I've seen with that downward curve of the tail on the lock plate. Glad that Philip offered his analysis of this feature. The seperate striking surface on the frizzen (battery) is quite common on these locks. It would be easier and less expensive to make this piece than to make a new frizzen. And, as mentioned, keeping the identification on the front of the frizzen. While this seperate striking face was usually wedged in place, some of the Eastern locks were actually held in place with a set-screw per the photos below.

Again, it's sure an interesting pistol with a multiple history. And a very interesting Thread. Thanks to all.

Fernando K : Yes, please stay with us. Your expertise is very much needed.
