An old wine bottle: French?

You know I have this blown bottle for such a long time that I don’t remember when and to whom it was bought…. Probably at the Belgrano flea market. Sure it was cheap but I was curious about it. There is a wonderful web page Historic Glass Bottle Identification & Information Website this tye of bottles are assigned as of French origin…. Because of the big “mountain” in the base that has been pushed up with an iron rod https://sha.org/bottle/bases.htm: I have been Reading and could be Belgian also. Perhaps around 1850. Around 25 cm tall.
