I think it's Chavet from late 40s. The booklet is from 1945 but the pieces could be from slightly later date as German National Socialists bombed Dortan during WW2 and destroyed some workshops.
@Walterbiensur could tell you much more about it, he the expert on French pieces.
And congrats on a very nice set! 
I have a few similar sets that I’ve long suspected are not Lardy but probably Chavet. Features like the turtle-necked bishop, low-rise knight pedestal, coupled with this knight head. The craftsmanship/finishing on these sets also seems to be a little finer than my typical Lardy sets. I have a Lowe set with the same 1945 booklet, but don’t think it dates the set to the year or even the decade. I Imagine they would use booklets with this copyright date until the booklet needed to be updated and reprinted. It would be interesting to see the range of other Lowe booklets with different copyright dates. If you could see the series of years, that could really help date sets.
I was hoping someone here with more expertise than me might be able to help me with this (This will be my first nice wooden set). I recently purchased a vintage set of pieces for what seemed like a pretty good price and I thought it was a Lardy, but the more I look at it (Particularly the knight) the more I wonder if it may be a Chavet. It came with a box labelled as E.S Lowe, and an instruction booklet dated 1945. The King is around 3.75 inches.
Bonus question: Is this an actual 1945 make and is it possible to narrow it down by month?
