You probably have English threads (look for "BSC" on the freewheel or the hub). As you undoubtedly have guessed, you do not have French threads.
If you have Italian threads, you can convert to an English freewheel, but because the groove profile differs, you cannot switch back and forth between English and Italian threading without risking stripping the threads on your rear hub.
