A somewhat interesting outside lock airgun. 13mm/.50 cal. Not sure how they know that it's French, other than being in France at the moment. Described as 18th century; certainly could be but the outside lock airguns had a long history from at least mid 18th century (and likely much earlier) till mid 19th century with, as far as known, little variation.
