Sorry, that is not correct. The letters are definitely 'S' (cursive 'L' was never written in that way) and 'F' and they stand for 'slow' and 'fast'.I believe the cursive letters "S" and "F" that you say are for "slow" and "fast" actually say "L" and "F", and they are the initals of the maker of your clock - L&F Moreau.
It's S and F, as from what I understand all (most?) carriage clocks have these 2 letters indicating speed adjustment. Curiously in our clocks this setting is inverted, as yours has F on the left side and S on the right.Wow, I have a clock very similar, also with no indication of the maker.

My clock must be a different maker because my Slow Fast indicators are a different (and much more humble) font. View attachment 666537
as for the numbers engraved on the movement, I think they were used when the movement was assembled to label the different parts.
if you look carefully you will see that the balance wheel is vertical in the clock shown in post #9, rather than horizontal (on a platform at the top of the clock) in most French clocks.
The arrow while not very well stamped is that of Couaillet.Jonathan and Rough – Thanks for the comments. After reading them I went back to the clock with my camera for a more thorough investigation. Using flash and zoom I was able to take a better photo of the arrow.
