Thank you again Hironobu
Very useful the links you provided to us.
So basis these links and other info you sent me , here are my comments :
- 48 mon : missing the secret marks. Most likely is a Wada A forgery
- 100 mon : missing the secret marks. This one is a Hirose B forgery. And to increase the value of its forgery Hirose made the stamp with inverted centre !
- 200 mon : the worst forgery among all ! It could be Wada B or Spiro.
- 400 mon : forgery of Plate I , early printing. Secret marks missing ! I guess is Wada A or Wada C .
