So that should be 7 tanks at 20 points a piece = 140 points.
Lovely stuff and well worth 140 points. I'm not really familiar with the H39, more commonly seeing the S35 and B1 bis. I'm sure there will be an epic clash between them and the blitzing 38Ts!
Congratulations on knocking over this part of your challenge! I've tagged you in the What a tanker! section as well.
