Wilma Bishop is a witch from Isle of Wight Detachment Group in the anime Strike Witches series.
This model we had here is made by Lahan, he is a Japanese pepakura designer that likes to built original chara, kancolle and strike witches model.
What great about his model is that aside from having a pdo for guidance, he also uploads assembling videos of each scale models on niconico . So if you got stuck, you can always watch the videos for help.
For this model you only need 5 sheets of paper and it is fairly easy to built. The scale is 1/7
