I'm guessing the spelling too. I mean to say, fowler flaps are what made the 38, in AH.
The 84 has them too, and it is great too.. I wonder what some planes like the 190D would be like with fowlers instead.. and why fowlers weren't more common.
If I understand right, their advantage is that they extend the wing area, in addition to increasing the AoA on a portion of the wing. If that's the case, I don't understand why they weren't a no brainer for at least a few of the LW planes...
