Hello
Please show all marks. If this pot is French, it will have a Minerva head mark in either an octagonal reserve (950 standard) or barrel-shaped reserve (800 standard). The Minerva should be stamped along the rim of the pot. Having this info will help to find the maker.
If the finial swivels open to insert a muddler, you have a chocolate pot. If not, it is a coffee pot. Both can have side handles.
Based on style alone, IMO your pot dates to the third quarter of the 19th C. It is not an 18th C item.
